Transposition and Permutation
Transposition and Permutation: In cryptography, transposition refers to rearranging the characters in a message, while permutation involves rearranging bits, bytes, or other parts of data according to a specific rule or system. Both techniques are used to obscure the content for security purposes.
Tunneling
Tunneling: Tunneling is a protocol that allows for the secure movement of data from one network to another. It involves encapsulating a network protocol within packets carried by the second network. Tunneling is often used in virtual private networks (VPNs) to secure data over untrusted networks like the internet.
Trapdoor function
Trapdoor function: A function that is easy to compute in one direction but believed to be difficult to compute in the opposite direction without special information, called a ‘trapdoor’. These functions are essential in the construction of encryption algorithms, particularly public-key cryptosystems.
Two-Factor Authentication
Two-Factor Authentication: A security measure that requires a user to provide two different types of credentials to verify their identity before they can access a system or data. This typically involves a combination of something the user knows (like a password), something the user has (like a physical token or a smartphone app), or something […]
Trike
Trike: A risk-based security auditing framework that focuses on modeling systems from a threat perspective. It aims to identify security risks by analyzing the intended behavior of the system and comparing it against potential security threats, thereby informing the development of security measures and controls.
Twofish
Twofish: A symmetric key block cipher known for its simplicity and speed. It was one of the five finalists in the Advanced Encryption Standard (AES) contest, where it was praised for its high security, good performance, and ease of implementation.
