Using the Miller-Rabin (probabilistic) primality test. NOTE: if bo (and only bo) had been either +1 OR -1, n would be prime (it was 263, in this example). BUT for b1, b2, and so on, +1 implies composite, -1 implies prime. Questions? Feel free to post them in the comments and I'll do my best to answer!

In number theory, integer factorization or prime factorization is the decomposition of a composite number into smaller non-trivial divisors, which when multiplied together equal the original integer. When the numbers are very large, no efficient, non-quantum integer factorization algorithm is known; an effort by several researchers concluded in 2009, factoring a 232-digit number (RSA-768), utilizing hundreds of machines over a span of two years. However, it has not been proven that no efficient algorithm exists. The presumed difficulty of this problem is at the heart of widely used algorithms in cryptography such as RSA. Many areas of mathematics and computer science have been brought to bear on the problem, including elliptic curves, algebraic number theory, and quantum computing.

Fundamentals of Computer Network Security This specialization in intended for IT professionals, computer programmers, managers, IT security professionals who like to move up ladder, who are seeking to develop network system security skills. Through four courses, we will cover the Design and Analyze Secure Networked Systems, Develop Secure Programs with Basic Cryptography and Crypto API, Hacking and Patching Web Applications, Perform Penetration Testing, and Secure Networked Systems with Firewall and IDS, which will prepare you to perform tasks as Cyber Security Engineer, IT Security Analyst, and Cyber Security Analyst. course 2 Basic Cryptography and Programming with Crypto API: About this course: In this MOOC, we will learn the basic concepts and principles of cryptography, apply basic cryptoanalysis to decrypt messages encrypted with mono-alphabetic substitution cipher, and discuss the strongest encryption technique of the one-time-pad and related quantum key distribution systems. We will also learn the efficient symmetric key cryptography algorithms for encrypting data, discuss the DES and AES standards, study the criteria for selecting AES standard, present the block cipher operating modes and discuss how they can prevent and detect the block swapping attacks, and examine how to defend against replay attacks. We will learn the Diffie-Hellman Symmetric Key Exchange Protocol to generate a symmetric key for two parties to communicate over insecure channel. We will learn the modular arithmetic and the Euler Totient Theorem to appreciate the RSA Asymmetric Crypto Algorithm, and use OpenSSL utility to realize the basic operations of RSA Crypto Algorithm. Armed with these knowledge, we learn how to use PHP Crypto API to write secure programs for encrypting and decrypting documents and for signing and verify documents. We then apply these techniques to enhance the registration process of a web site which ensures the account created is actually requested by the owner of the email account. Asymmetric Key Cryptography In this module we will learn the modular arithmetic, the Euler Totient Theorm, the RSA Asymmetric Crypto Algorithm, use OpenSSL to realize the basic operations of RSA Crypto Algorithm, and Diffie-Hellman Symmetric Key Exchange Protocol to derive session keys.

In this paper, we introduce a primitive known as Verifiable Oblivious Transfer. It is similar to oblivious transfer except that the sender is committed to its input. We then generate protocols for Generalized Oblivious Transfer by secret sharing using the Verifiable Oblivious Transfer primitive based on previous work. The protocols are universally composable. The GOT protocol is used to instantiate Batch Single-Choice Cut-And-Choose OT which in conjunction with a modification to the main protocol of [LP11], achieves constant round secure function evaluation based on Yao's Garbled Circuit. In addition, the idea of GOT is used in conjunction with linear secret sharing and commitments to instantiate a primitive known as Multi-Sender K-Out-of-N OT. This primitive is the most important building block of the optimization of the IPS compiler presented in [LOP11]. In contrast to their specific computational assumptions, our protocols only require black-box Verifiable OT. In addition, the GOT protocols can be used to execute Priced Oblivious Transfer.

http://demonstrations.wolfram.com/Pseudoprime/ The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. Fermat's little theorem (FLT) states that for any prime number p and coprime base a, a^p=a (mod p). If this congruence fails, then p cannot be prime. Using FLT as a primality test seems promising because it distinguishes primes from nonprimes... Contributed by: Ed Pegg Jr

ECC2K-130 is the smallest unsolved Certicom discrete-logarithm challenge. Certicom originally stated that breaking ECC2K-130 was 'infeasible' and would require 2700000000 machine days. This talk reports on an ongoing joint project by researchers from 12 different universities to break ECC2K-130. The project has increased our knowledge of the mathematical speedups for attacking elliptic-curve cryptosystems, has led to a new representation for finite fields in 'optimal polynomial bases', and has led to a better understanding of the randomness of pseudorandom walks used in Pollard's rho method. The project has produced optimized implementations of a highly tuned iteration function for different platforms ranging from standard CPUs to customized FPGA clusters. These optimizations have moved the ECC2K-130 computation to the range of feasibility. The computation would finish in only two years using 1595 standard PCs, or 1231 PlayStation 3 game consoles, or 534 GTX 295 graphics cards, or 308 XC3S5000 FPGAs, or any combination of the above. We are now actively performing the computations. See our twitter page for updates.

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime, because the only ways of writing it as a product, or , involve 5 itself. However, 6 is composite, because it is the product of two numbers that are both smaller than 6. Primes are central in number theory, because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple, but slow method of checking the primality of a given number n, called trial division, tests whether n is a multiple of any integer between 2 and \sqrt. Faster algorithms include the Miller–Rabin primality test, which is fast, but has a small chance of error, and the AKS primality test, which always produces the correc... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:02:45 Definition and examples 00:05:10 History 00:09:11 Primality of one 00:11:05 Unique factorization ____________________________________ Copyright WikiVidi.

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.
