WebThere are two types of encryption systems: secret-key and public-key systems (see Figure 1 ). In secret-key encryption, also referred to as symmetric cryptography, the same key is … In cryptography, a cryptosystem is a suite of cryptographic algorithms needed to implement a particular security service, such as confidentiality (encryption). Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption. The term cipher (sometimes cypher) is often used to refer to a pair of algorithms, one for encryption and one for decryption.
