Discrete logarithm. In mathematics, for given real numbers a and b, the logarithm log b a is a number x such that bx = a. Analogously, in any group G, powers bk can be defined for all integers k, and the discrete logarithm log b a is an integer k such that bk = a. In number theory, the more commonly used term is index: we can write x = ind r a ...
Shamir's secret sharing (SSS) is an efficient secret sharing algorithm for distributing private information (the "secret") among a group. The secret cannot be revealed unless a quorum of the group acts together to pool their knowledge. To achieve this, the secret is mathematically divided into parts (the "shares") from which the secret can be ...
Having many users look at source code does not guarantee that security flaws will be found and fixed. Metrics and models. There are a variety of models and metrics to measure the security of a system. These are a few methods that can be used to measure the security of software systems. Number of days between vulnerabilities
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [68] and metaobjects ). [69]
e. Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
A security log is used to track security-related information on a computer system. Examples include: Windows Security Log. Internet Connection Firewall security log. According to Stefan Axelsson, "Most UNIX installations do not run any form of security logging software, mainly because the security logging facilities are expensive in terms of ...

Pollard's rho algorithm for logarithms is an algorithm introduced by John Pollard in 1978 to solve the discrete logarithm problem, analogous to Pollard's rho algorithm to solve the integer factorization problem. The goal is to compute such that , where belongs to a cyclic group generated by . The algorithm computes integers , , , and such that .
