Cryptosystem and its components

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. Therefore, the term cryptosystem is most … WebApr 12, 2024 · Therefore, the key space of the cryptosystem is 2 2 × W × H, where W = width and H = height of the input image. The key space for Fig. 6 (a) is (2 320 × 500 × 3 × 2) which is significantly large. A secure cryptosystem must provide a substantially different encrypted image if any modification (even a single bit) is performed in the original ...
