Text Encryption Algorithm for Secure Communication

In this paper, a new encryption algorithm is presented, designed for secure text message communication. The proposed cryptographic system is based on pseudorandom generator, constructed with two chaotic maps. For security level determination, extensive cryptographic analysis is performed. The evaluation of the presented cryptographic scheme includes the results of statistical testing, key space analysis, frequency analysis, common correlation analysis, entropy analysis, key sensitivity analysis and speed performance. The results are presented and explained in this paper.
