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:
“Well may Mr. [David] Garrick be so celebrated, so universally admired—I had not any idea of so great a performer. Such ease! such vivacity in his manner! such grace in his motions! such fire and meaning in his eyes!—I could hardly believe he had studied a written part, for every word seemed uttered from the impulse of the moment. ... his voice—so clear, so melodious, yet so wonderfully various in its tones!”
—Frances Burney (1752–1840)
“The hard truth is that what may be acceptable in elite culture may not be acceptable in mass culture, that tastes which pose only innocent ethical issues as the property of a minority become corrupting when they become more established. Taste is context, and the context has changed.”
—Susan Sontag (b. 1933)
