Method for comparative performance analyze of encryption algorithms used in public key infrastructure for secure transmitting of audio information

摘要

In this article it will be analyzed the characteristics of the symmetric encryption algorithms Blowfish, Advanced Encryption Standard, Data Encryption Standard and Triple Data Encryption Standard for securing audio information using developed method for measuring their performance. The results will be compared with already examined ones based on the developed method for performance evaluation of the asymmetric encryption algorithm Rivest-Shamir-Adleman with which their advantages and disadvantages will be analyzed. For that purpose the resources provided by the Java programming language will be used.
