Secure Audio Information Transmission with Encryption Algorithms in PKI

Audio information transmission via communication systems must be secure. There are a number of general wide spread methods for secure transmission of audio information like watermarking, steganography, etc. Despite that, it is suitable to develop and test other methods for secure transmission of audio information, based on general principles of secure transmission of information. One of these general methods is Public Key Infrastructure (PKI). Therefore, the goal of this article is to apply PKI for secure audio information transmission, choosing the appropriate and effective encryption algorithms and communication channel characteristics, corresponding to the specifics of the transmitted audio information.
