Virtualization software is increasingly a part of the infrastructure behind our online activities. The companies and institutions that produce online content are taking advantage of the "infrastructure as a service" cloud computing model to obtain cheap and reliable computing power. These content producers rent compute time from the cloud provider during which they can run their entire software stack on the cloud provider's server. The cloud providers are able to provide cheap computing power by letting multiple client operating systems share a single physical machine, and they use virtualization technology to do that. The virtualization layer also provides isolation between guests, protecting each from unwanted access by the co-tenants. In this talk, Cynthia Sturton, Ph.D candidate at the University of California Berkeley, discusses her research toward verifying the security of this virtualization layer, and in particular, the isolation properties.

However, Ethereum Certification Training is best suited for the below mentioned profiles:- Software Developers Full Stack Developers Why should you go for this ethereum developer's course? Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk. Using Ethereum, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone. You can even use the token you created earlier to keep track of the distribution of rewards.

Clip 6/6 Speaker: Danfeng Yao · Brown University In outsourced content publishing, the data owner gives the content to a service provider who answers requests from users. Similarly, in outsourced databases, the data owner delegates a service provider to answer queries. Outsourcing enables fast and fault-tolerant delivery of information. However, since service providers in outsourced systems may not be trusted by users, the user needs to verify the integrity of information obtained. First, I present a cryptographic solution for the verification of pseudonymized documents. A document can be pseudonymized by the service provider on the fly, based on the data owner's policies and the user's access permissions. Our pseudonym protocol is simple and efficient, and only requires the data owner to prepare and sign the document once. Second, I present a solution for integrity verification of database aggregate queries, such as sum and max. We design proofs of correctness and completeness of aggregate results. What makes the problem challenging is that individual data entries may be sensitive (such as in medical databases), and should not be revealed to the user. We give cryptographic protocols to support verification of query results in a privacy-preserving fashion. For more information go to the Cerias website (http://bit.ly/dsFCBF)

Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional ("symmetric") cryptography which relies on the same key to perform both. Public-key algorithms are based on mathematical problems which currently admit no efficient solution that are inherent in certain integer factorization, discrete logarithm, and elliptic curve relationships. It is computationally easy for a user to generate their own public and private key-pair and to use them for encryption and decryption. The strength lies in the fact that it is "impossible" (computationally infeasible) for a properly generated private key to be determined from its corresponding public key. Thus the public key may be published without compromising security, whereas the private key must not be revealed to anyone not authorized to read messages or perform digital signatures. Public key algorithms, unlike symmetric key algorithms, do not require a secure initial exchange of one (or more) secret keys between the parties. This video is targeted to blind users.

Bugs in security-critical system software already cost society billions of dollars, and the need for secure software is increasing as more devices are connected to the Internet. This session will outline the security needs of network-connected systems and explore how formal verification can help secure them. We’ll present research on bringing high-value security to low-cost devices, particularly those powered by microcontrollers – a class of devices ill-prepared for the security challenges of Internet connectivity. We’ll also discuss advances in verification tools and techniques that lead to real, usable verified software, with an emphasis on critical systems such as distributed and operating systems, cloud infrastructure, networking protocols and cryptography. Finally, we’ll present an overview of the Azure Sphere product as part of Microsoft’s efforts to secure MCU-based devices.
