    abstract     = {Summary: Recently a chaotic cryptographic scheme based on composition maps was proposed. This paper studies the security of the scheme and reports the following problems: (1) the scheme can be broken by a differential attack with $6 + \lceil \log _{L}(MN)\rceil $ chosen plaintexts, where $MN$ is the size of the plaintext and $L$ is the number of different elements in plaintext; (2)the two composition maps both do not work as a secure and efficient source of random numbers; (3)the scheme is not sensitive to the changes of the plaintext.},
