KR advantage : ウィキペディア英語版 | KR advantage In cryptography, the key-recovery advantage (KR advantage) of a particular algorithm is a measure of how effective an algorithm can mount a key-recovery attack. Consequently, the maximum key-recovery advantage attainable by any algorithm with a fixed amount of computational resources is a measure of how difficult it is to recover a cipher's key. It is defined as the probability that the adversary algorithm can guess a cipher's randomly selected key, given a fixed amount of computational resources.〔Goldwasser, S. and Bellare, M. ("Lecture Notes on Cryptography" ). Summer course on cryptography, MIT, 1996-2001〕 An extremely low KR advantage is essential for an encryption scheme's security. == References ==
