Mobile: (0) 9952649690, Email: [email protected], web: www.jpinfotech.org, Blog: www.jpinfotech.blogspot.com Most anomaly detection systems rely on machine learning algorithms to derive a model of normality that is later used to detect suspicious events. Some works conducted over the last years have pointed out that such algorithms are generally susceptible to deception, notably in the form of attacks carefully constructed to evade detection. Various learning schemes have been proposed to overcome this weakness. One such system is Keyed IDS (KIDS), introduced at DIMVA “10. KIDS” core idea is akin to the functioning of some cryptographic primitives, namely to introduce a secret element (the key) into the scheme so that some operations are infeasible without knowing it. In KIDS the learned model and the computation of the anomaly score are both key-dependent, a fact which presumably prevents an attacker from creating evasion attacks. In this work we show that recovering the key is extremely simple provided that the attacker can interact with KIDS and get feedback about probing requests. We present realistic attacks for two different adversarial settings and show that recovering the key requires only a small amount of queries, which indicates that KIDS does not meet the claimed security properties. We finally revisit KIDS’ central idea and provide heuristic arguments about its suitability and limitations.

IOHK | Developing a secure proof of stake algorithm
 
02:46
Prof Aggelos Kiayias is the Chair in Cyber Security and Privacy at the University of Edinburgh. His research interests are in computer security, information security, applied cryptography and foundations of cryptography with a particular emphasis in blockchain technologies and distributed systems, e-voting and secure multiparty protocols as well as privacy and identity management. https://iohk.io/team/aggelos-kiayias/ Developing a secure proof of stake algorithm is one of the big challenges in cryptocurrency, and a proposed solution to this problem won the attention of the academic community. Several hundred cryptographers from around the world arrived at the University of California Santa Barbara on Sunday for the flagship annual event of their field, Crypto 2017. Over several days, they present cutting edge research for the scrutiny of their peers, while in the evenings they continue discussions with friends and colleagues over dinner on the university campus, with the inspiring backdrop of the Santa Ynez mountains meeting the Pacific ocean behind them. https://iohk.io/press/ Ouroboros, developed by a team led by IOHK chief scientist Aggelos Kiayias, made it through a tough admission process for the prestigious conference. This year, 311 papers were submitted and of those 72 were accepted. Only three papers at the conference were on the subject of blockchain. All three papers were supported by IOHK funding. Speaking after his presentation, Professor Kiayias said: “We’re very happy that we had the opportunity to present Ouroboros at the conference. The protocol and especially its security analysis were very well received by fellow cryptographers.” “Our next steps will be to focus on the next version of the protocol, Ouroboros Praos which improves even further the security and performance characteristics of the protocol.” The Ouroboros protocol stands out as the first proof of stake algorithm that is provably secure, meaning that it offers security guarantees that are mathematically proven. This is essential for a protocol that is intended to be used in cryptocurrency, an infrastructure that must be relied on to carry billions of dollars worth of value. In addition to security, if blockchains are going to become infrastructure for new financial systems they must be able to comfortably handle millions of users. The key to scaling up is proof of stake, a far more energy efficient and cost effective algorithm, and as such this research represents a significant step forward in cryptography. Ouroboros also has the distinction of being implemented – the protocol will be an integral part of Cardano, a blockchain system currently in development. https://iohk.io/research/papers/#XJ6MHFXX https://iohk.io/projects/cardano/ There were two other papers presented at the bitcoin session on Monday. The Bitcoin Backbone Protocol with Chains of Variable Difficulty, was produced by a team of three researchers and included Prof Kiayias. It is a continuation of previous research into Bitcoin, which was itself the first work to prove security properties of its blockchain. A third paper on the subject of bitcoin was presented, Bitcoin as a Transaction Ledger: A Composable Treatment. Other notable talks at the conference included a presentation by John Martinis, an expert on quantum computing and former physics professor at the University of California Santa Barbara, who is now working at Google to build a quantum computer. Leading cryptographers at the conference included Whitfield Diffie, pioneer of the public key cryptography that made Bitcoin possible, and Ron Rivest, Adi Shamir, and Leonard Adleman, who came up with the RSA public-key cryptosystem that is widely used for secure data transmission. https://www.forbes.com/sites/amycastor/2017/08/23/at-crypto-2017-blockchain-presentations-focus-on-proofs-not-concepts/#6e558d1a7b70 https://iohk.io/team/aggelos-kiayias/ https://iohk.io/team/bernardo-david/ https://iohk.io/team/peter-gazi/ -- Input Output See more at: https://iohk.io Get our latest news updates: https://iohk.io/blog/ Meet the team: https://iohk.io/team/ Learn about our projects: https://iohk.io/projects/cardano/ Read our papers: http://iohk.link/paper-ouroboros Visit our library: https://iohk.io/research/library/ In the press: https://iohk.io/press/ Work with us: https://iohk.io/careers/ See more on Cardano: https://iohk.io/projects/cardano/ --

With their increasing computational power and storage capacity, smartphones allow end users to perform several tasks and be always updated while on the move. Companies are willing to support employee-owned smartphones because of the increase in productivity of their employees. However, security concerns about data sharing, leakage and loss have hindered the adoption of smartphones for corporate use. In this paper we present MOSES, a policy-based framework for enforcing software isolation of applications and data on the Android platform. In MOSES, it is possible to define distinct Security Profiles within a single smartphone. Each security profile is associated with a set of policies that control the access to applications and data. Profiles are not predefined or hardcoded, they can be specified and applied at any time. One of the main characteristics of MOSES is the dynamic switching from one security profile to another. We run a thorough set of experiments using our full implementation of MOSES. The results of the experiments confirm the feasibility of our proposal.

Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search

Generating Searchable Public-Key Ciphertexts with Hidden Structures for Fast Keyword Search in .NET To get this project in ONLINE or through TRAINING Sessions, Contact: JP INFOTECH, Old No.31, New No.86, 1st Floor, 1st Avenue, Ashok Pillar, Chennai -83.Landmark: Next to Kotak Mahendra Bank. Pondicherry Office: JP INFOTECH, #45, Kamaraj Salai,Thattanchavady, Puducherry -9.Landmark: Next to VVP Nagar Arch. Mobile: (0) 9952649690, Email: [email protected], web: www.jpinfotech.org, Blog: www.jpinfotech.blogspot.com Existing semantically secure public-key searchable encryption schemes take search time linear with the total number of the ciphertexts. This makes retrieval from large-scale databases prohibitive. To alleviate this problem, this paper proposes Searchable Public-Key Ciphertexts with Hidden Structures (SPCHS) for keyword search as fast as possible without sacrificing semantic security of the encrypted keywords. In SPCHS, all keyword-searchable ciphertexts are structured by hidden relations, and with the search trapdoor corresponding to a keyword, the minimum information of the relations is disclosed to a search algorithm as the guidance to find all matching ciphertexts efficiently. We construct a SPCHS scheme from scratch in which the ciphertexts have a hidden star-like structure. We prove our scheme to be semantically secure in the Random Oracle (RO) model. The search complexity of our scheme is dependent on the actual number of the ciphertexts containing the queried keyword, rather than the number of all ciphertexts. Finally, we present a generic SPCHS construction from anonymous identity-based encryption and collision-free full-identity malleable Identity-Based Key Encapsulation Mechanism (IBKEM) with anonymity. We illustrate two collision-free full-identity malleable IBKEM instances, which are semantically secure and anonymous, respectively, in the RO and standard models. The latter instance enables us to construct an SPCHS scheme with semantic security in the standard model.

Extracting Speed Spectrum Hidden Data From Digital Media
 
01:24
Title: Extracting Spread-Spectrum Hidden Data from Digital Media Domain: Networking - Steganography Key Features: 1. We consider the problem of extracting blindly data embedded over a wide band in a spectrum (transform) domain of a digital medium (image, audio, video). We develop a novel multicarrier/ signature iterative generalized least-squares (M-IGLS) core procedure to seek unknown data hidden in hosts via multicarrier spread-spectrum embedding. 2. Neither the original host nor the embedding carriers are assumed available. Experimental studies on images show that the developed algorithm can achieve recovery probability of error close to what may be attained with known embedding carriers and host autocorrelation matrix. 3. We propose the information hiding concept to reduce the risk of using cryptographic algorithms alone. Data hiding techniques embed information into another medium making it imperceptible to others, except for those that are meant to receive the hidden information and are aware of it presence. 4. It focuses on methods of hidden data in which cryptographic algorithms are combined with the information hiding techniques to increase the security of transmitted data. We focus our attention on the blind recovery of secret data hidden in medium hosts via multi-carrier/signature direct-sequence spread-spectrum transform domain embedding. MODULE DESCRIPTION Steganography: Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol Digital steganography can hide confidential data (i.e. secret files) very securely by embedding them into some media data called "vessel data." The vessel data is also referred to as "carrier, cover, or dummy data". In Steganography images used for vessel data. The embedding operation in practice is to replace the "complex areas" on the bit planes of the vessel image with the confidential data. The most important aspect of Steganography is that the embedding capacity is very large. For a 'normal' image, roughly 50% of the data might be replaceable with secret data before image degradation becomes apparent. Multi-Carrier Spread Spectrum Embedding: The technique of spread spectrum may allow partly to fulfill the above requirements. Advantages of spread spectrum techniques are widely known: Immunity against multi-path distortion, no need for fiequency planning, high flexibility and variable data rate transmission. The capability of minimising multiple access interference in direct-sequence code- division-multiple-access system is given by the cross-correlation properties of spreading codes. In the case of multi-path propagation the capability of distinguishing one component fiom thers in the composite received signal is offered by the auto-correlation roperties of the spreading codes. Image encryption and watermarking: The host image is an 8-bit or higher grey level image which must ideally be the same size as the plaintext image or else resized accordingly using the same proportions. Pre-conditioning the cipher and the convolution processes are undertaken using a Discrete Fourier Transform (DFT). The output will include negative floating point numbers upon taking the real component of a complex array. The array must be rectified by adding the largest negative value in the output array to the same array before normalization. For color host images, the binary cipher text can be inserted into one or all of the RGB components. The binary plaintext image should have homogeneous margins to minimize the effects of ringing due to 'edge effects' when processing the data using Fourier transform. Image decryption and extraction: (i) The correlation operation should be undertaken using a DFT. (ii) For color images, the data is decomposed into each RGB component and each 1-bit layer is extracted and correlated with the appropriate cipher. (iii) The output obtained in Step 3 has a low dynamic range and therefore requires to be quantized into an 8-bit image based on floating point numbers within the range max (array)-min (array).

Bufferbloat: Dark Buffers in the Internet
 
01:00:54
Google Tech Talk (more info below) April 26, 3011 Presented by Jim Gettys. ABSTRACT VOIP and teleconferencing often perform much more poorly on today's Internet than the Internet of a decade ago, despite great gains in bandwidth. Lots of fiber, cheap memory, smart hardware, variability of wireless thoughput, changes in web browser behaviour, changes in TCP implementations, and a focus on benchmarking Internet performance solely by bandwidth, and engineer's natural reluctance to drop packets have conspired to encourage papering over problems by adding buffers; each of which may introduce latency when filled. Buffering mistakes have been made in all technologies: operating systems, home routers both wired and wireless, broadband equipment, corporate networks, 3G networks and parts of the core Internet itself. The mistaken quest to never drop packets has destroyed interactivity under load, and often results in actual higher packet loss, as TCP's congestion avoidance algorithms have been defeated by these buffers. The lessons of the "RED manifesto" of 1997 have been forgotten or never learned by a new generation of engineers. Full solutions require careful queue management, and that management should be everywhere; we no longer have the luxury to think that this is a problem solely of Internet routers. I will describe some of the mitigations and solutions to this problem, and how you can at least make your home network and systems behave the way they should.

Certificateless Remote Anonymous Authentication Schemes for Wireless Body Area Networks

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Certificateless Remote Anonymous Authentication Schemes for Wireless Body Area Networks Wireless body area network (WBAN) has been recognized as one of the promising wireless sensor technologies for improving healthcare service, thanks to its capability of seamlessly and continuously exchanging medical information in real time. However, the lack of a clear in-depth defense line in such a new networking paradigm would make its potential users worry about the leakage of their private information, especially to those unauthenticated or even malicious adversaries. In this paper, we present a pair of efficient and light-weight authentication protocols to enable remote WBAN users to anonymously enjoy healthcare service. In particular, our authentication protocols are rooted with a novel certificateless signature (CLS) scheme, which is computational, efficient, and provably secure against existential forgery on adaptively chosen message attack in the random oracle model. Also, our designs ensure that application or service providers have no privilege to disclose the real identities of users. Even the network manager, which serves as private key generator in the authentication protocols, is prevented from impersonating legitimate users. The performance of our designs is evaluated through both theoretic analysis and experimental simulations, and the comparative studies demonstrate that they outperform the existing schemes in terms of better trade-off between desirable security properties and computational overhead, nicely meeting the needs of WBANs.

Tiny Functions for Codecs, Compilation, and (maybe) soon Everything
 
01:24:01
Networks, applications, and media codecs frequently treat one another as strangers. By expressing large systems as compositions of small, pure functions, we've found it's possible to achieve tighter couplings between these components, improving performance without giving up modularity or the ability to debug. I'll discuss our experience with systems that demonstrate this basic idea: ExCamera (NSDI 2017) parallelizes video encoding into thousands of tiny tasks, each handling a fraction of a second of video, much shorter than the interval between key frames, and executing in parallel on AWS Lambda. This was the first system to demonstrate "burst-parallel" thousands-way computation on functions-as-a-service infrastructure. Salsify (NSDI 2018) is a low-latency network video system that uses a purely functional video codec to explore execution paths of the encoder without committing to them, allowing it to closely match the capacity estimates from a video-aware transport protocol. This architecture outperforms more loosely-coupled applications -- Skype, Facetime, Hangouts, WebRTC -- in delay and visual quality, and suggests that while improvements in video codecs may have reached the point of diminishing returns, video systems still have low-hanging fruit. Lepton (NSDI 2017) uses a purely functional JPEG/VP8 transcoder to compress images in parallel across a distributed network filesystem with arbitrary block boundaries. This free-software system is in production at Dropbox and has compressed, by 23%, more than 200 petabytes of user JPEGs. Based on our experience, we propose an intermediate representation for interactive lambda computing, called cloud "thunks" -- stateless closures that describe their data-dependencies by content-hash, separating the specification of an algorithm from its schedule and execution. We have created a tool that extracts this IR from off-the-shelf software build systems, letting the user treat a FaaS service like a 5,000-core build farm with global memoization of results. Expressing systems and protocols as compositions of small, pure functions has the potential to lead to a wave of "general-purpose" lambda computing, permitting us to transform everyday time-consuming operations into large numbers of functions executing with massive parallelism for short durations in the cloud.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

In contrast, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling. Assembly language may also be called symbolic machine code.Assembly language usually has one statement per machine instruction, but assembler directives, macros and symbolic labels of program and memory locations are often also supported. Assembly code is converted into executable machine code by a utility program referred to as an assembler. The conversion process is referred to as assembly, or assembling the source code.
