Performance Evaluation of Symmetric Key Cryptography Algorithms

With growth of Technology, With growth of technology, the needs for data and information security over communication channels are necessary. Providing information security in marine environment includes communication between ships and also ships with ground station are one of the most important issues in information security. In order to provide Confidentiality, symmetric key cryptography algorithms such DES, 3DES, IDEA, RC6, Serpent and AES are presented by researchers. Different reports in literature are presented by researchers in order to compare the performance of these algorithms. Despite various considerations, the needs for deep comparison of these algorithms are needed. Therefore in this paper, deep consideration and comparison in the points of architecture, flexibility, security and speed of these algorithms are done. Based on the achieved results, the appropriate algorithm can be employed based on required flexibility, speed or desired levels of security. The result of implementation and comparison shows the advantages of AES algorithm in provided security and RC6 in speed of execution.
