Title: | Cryptanalysis of an image encryption scheme | Authors: | Li, S Li, C Lo, KT Chen, G |
Issue Date: | Oct-2006 | Source: | Journal of electronic imaging, Oct.-Dec. 2006, v. 15, no. 4, 043012, p. 1-13 | Abstract: | 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 to show the feasibility of a proposed chosen-plaintext attack. In addition, some other minor problems of the joint compression-encryption scheme are also pointed out. | Keywords: | Image coding Cryptography Data compression |
