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.
Trojan horse
Trojan horse: A type of malicious program that disguises itself as legitimate and often desirable software to deceive users into downloading and installing it. Once inside the system, it can execute harmful tasks such as stealing data, compromising system integrity, or creating backdoors for unauthorized access.
Two-person control
Two-person control: A security concept used to maintain high levels of safety and integrity by ensuring that two or more individuals are required to perform certain sensitive or high-risk tasks. This technique prevents a single individual from having sole authority or access and is often applied to prevent fraudulent activities or unauthorized actions.
