Using Circle Map for Audio Encryption Algorithm

Krasimir Kordov, Lachezar Bonchev


In this paper we propose audio encryption algorithm based on standard circle map. The proposed scheme contains bit level sample permutation using pseudorandom generator. Provided cryptanalysis includes number of tests demonstrating the security of proposed encryption algorithm.
