Study on the design of MDS-M2 Twofish cryptographic algorithm adapted to wireless communication

Wireless communication environment that compare to wire communication environment at the process speed and an power consumption respect has a very weak security mechanism. Therefore, we designed Twofish cryptographic algorithm in order to strengthen security of wireless communication environment in this paper. 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 Twofish cryptosystem that compares to MDS block of a Twofish 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. Proposed MDS-M2 Twofish cryptographic algorithm than the existing Twofish cryptographic algorithm by the simulation results confirmed a performance improvement of 11%. Therefore, we are considered the security system that the Twofish cryptographic system used an improved MDS-M2 block was very suitable for wireless communication environment.
