WebIn creating a new cryptosystem, security is a primary concern. The intercepting party may want to either read a particular message, ﬁnd the key to read all transferred mes sages, corrupt the message before it gets to its receiver, or pretend to be the sender and communicate with the receiver without his or her knowledge. 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 …
