Which of … WebCryptoperiod - A cryptoperiod is a specific time span during which a cryptographic key setting remains in effect. A key uses an algorithm to create ciphertext from plaintext and, for the receiver of the encrypted text, to decipher it. Once the cryptoperiod ends, the key is no longer available for either encryption or decryption.4

A cryptoperiod is the time span during which a specific cryptographic key is authorized for use. Common government guidelines range from 1 to 3 years for asymmetric cryptography, and 1 day to 7 days for symmetric cipher traffic keys. Factors to consider include the strength of the underlying encryption algorithm, key length, the likelihood of compromise through a security breach and the availability of mechanisms of revoki… WebQuestion: a) Cryptoperiods A cryptographic key is a value (essentially a random string of bits) that serves as input to an algorithm, which then transforms plain text into ciphertext (and vice versa for decryption). One of the important characteristics that determines key strength is its cryptoperiod [1]. Or the length of time for which the key is authorised for use.
