%X In order to verify the security of an image encryption algorithm based on Logistic chaotic map and Chen hyper-chao-tic system proposed in literature, discussed security analyses of the algorithm and proposed the measures of known plaintext attacks and chosen plaintext attacks for random-sized encrypted images . Besides, pointed out the essential weakness of the algorithm and provided some suggestions to improve its security.
