Implementation of Secure Master Using Modified Twofish Algorithm in FPGA Devices
In this paper a novel VLSI architecture of the modified Twofish block cipher is presented. Twofish is one of the most secure cryptographic algorithms. The characteristic features of the Twofish Algorithm are good security margin, fast encryption/decryption in software, moderately fast in hardware and moderate flexibility. Designed Twofish cryptographic algorithm improved the existing MDS block with a MDS-M2 block that improved a process speed, and decreased complexity and power consumption. MDS-M2 block of the designed Two fish cryptosystem that compares to MDS block of a Two fish cryptographic system used in wire communication is a little processed the number of operation and system structure is simple, so a complexity duty is very low.
