Cryptanalysis of an image encryption scheme
We present cryptanalysis of an image encryption scheme, which is based on the base-switching (BS) lossless compression algorithm. The following conclusions are reached: 1. the size of the key space, i.e., the security against brute-force attacks, was greatly overestimated by the designers; and 2. the scheme is not secure against known/chosen-plaintext/ciphertext attacks. A real example is given...
متن کاملCryptanalysis of RCES/RSES Image Encryption Scheme
Recently, a chaos-based image encryption scheme called RCES (also called RSES) was proposed. This paper analyzes the security of RCES, and points out that it is insecure against the known/chosen-plaintext attacks: the number of required known/chosen plain-images is only one or two. In addition, the security of RCES against the brute-force attack was overestimated. Both theoretical and experimen...
متن کاملOn the cryptanalysis of Fridrich's chaotic image encryption scheme
Utilizing complex dynamics of chaotic maps and systems in encryption was studied comprehensively in the past two and a half decades. In 1989, Fridrich’s chaotic image encryption scheme was designed by iterating chaotic position permutation and value substitution some rounds, which received intensive attention in the field of chaos-based cryptography. In 2010, Solak et al. proposed a chosen-ciph...
متن کاملImproved Cryptanalysis of CMC Chaotic Image Encryption Scheme
Recently, chaos has attracted much attention in the field of cryptography. To study the security with a known image of a symmetric image encryption scheme, the attack algorithm of equivalent key is given. We give the known image attacks under different other conditions to obtain the equivalent key. The concrete step and complexity of the attack algorithm is given. So the symmetric image encrypt...
