Cryptosystem - Meaning in The Context of Cryptography

Meaning in The Context of Cryptography

In this meaning, a cryptosystem refers to a suite of algorithms needed to implement a particular form of encryption and decryption.

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 often used when the key generation algorithm is important. For this reason, the term "cryptosystem" is commonly used to refer to public key techniques; however both "cipher" and "cryptosystem" are used for symmetric key techniques.

Famous quotes containing the words meaning and/or context:

    We must leave our pets at home, when we go into the street, and meet men on broad grounds of good meaning and good sense.
    Ralph Waldo Emerson (1803–1882)

    Parents are led to believe that they must be consistent, that is, always respond to the same issue the same way. Consistency is good up to a point but your child also needs to understand context and subtlety . . . much of adult life is governed by context: what is appropriate in one setting is not appropriate in another; the way something is said may be more important than what is said. . . .
    Stanley I. Greenspan (20th century)
