Analysis and Comparison of Symmetric Key Cryptographic Algorithms on FPGA

Abstract

Data security is considered as one of the prime concern for every communication systems. Cryptography has come up as a resolution which plays a dynamic role in data security against various data attacks. The cryptography is most significant feature of communications security and becoming an vital building block for network security. This security mechanism uses some algorithms to convert readable data into unreadable data text which can be only accessed by intended receiver. In this paper the implementation of some algorithms is done such as Triple Data Encryption Standard (TDES), International Data Encryption Algorithm (IDEA), Data Encryption Standard (DES) and Blowfish algorithm block ciphers for encryption as well as decryption process using Xilinx 14.5 tool in Verilog as programming language and comparison of algorithms is carried out with performance parameters such as area utilization, power consumption, encryption and decryption time using Spartan6 FPGA device.
