Carlisle Adams/Stafford Tavares (CAST)
Carlisle Adams/Stafford Tavares (CAST): A series of symmetric encryption algorithms, including CAST-128 and CAST-256. Named after their developers, Carlisle Adams and Stafford Tavares, these algorithms are used to secure data during transmission or storage, ensuring confidentiality and preventing unauthorized access. CAST-128 is commonly used in various encryption protocols, including Secure Shell (SSH) and OpenVPN.
Certificate Revocation List (CRL)
Certificate Revocation List (CRL): A document maintained and published by a Certificate Authority listing digital certificates that have been revoked before their expiration date. Regularly updated, a CRL ensures that revoked certificates are not trusted by services, playing a crucial role in upholding the trust and security of digital transactions and communications.
Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)
Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA): A protocol used for controlling traffic in wireless networks to prevent collisions or simultaneous data transmissions that can cause data corruption. Before sending data, devices using CSMA/CA first check if the transmission medium is free. If it’s occupied, the device waits for a random period before checking […]
Certificate Revocation
Certificate Revocation: The process of declaring a digital certificate as no longer valid before its scheduled expiration date. This can occur due to a number of reasons such as the certificate’s private key being compromised, the certificate being issued in error, or the certificate holder no longer requiring the certificate. The revocation is typically handled […]
Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
Carrier Sense Multiple Access with Collision Detection (CSMA/CD): A network protocol that operates at the data link layer (Layer 2) of the OSI model, which manages communication between devices in a wired network, such as Ethernet. The protocol allows devices to detect whether the shared communication channel is busy before attempting to transmit data, thus […]
Certificate
Certificate: Often referred to as a digital certificate or a public key certificate, a certificate is a digital document that binds a public key to an identity. This document is used in various forms of online transactions and communications to prove the identity of an entity, like a person, company, or server. Certificates play a […]
