Chosen plaintext attacking "cryptanalysis of hyper-chaotic image encryption algorithm and its improved version"
摘要
Abstract
This paper introduced chosen plaintext attack. The target of the attack was an image encryption algorithm based on a hyper chaotic system whose disadvantages were vulnerable encryption methods of choosing elementary transformation and ex-clusive-or operation. Attack algorithm in which three characteristic plaintext matrices were given and the encryption key was unknown was utilized to attack the target algorithm. According to the result, chosen plaintext attack can decode this algorithm.关键词
