摘要：
Triple DES is widely used in various cryptographic applications and wireless protocol security layers. This paper analyzes the DES and triple DES algorithms, proposes a design approach of reconfigurable triple DES system based on reconfigurable hardware; and develops a method of key generation with the genetic algorithm which uses 64 bits key to realize triple DES algorithm. The reconfigurable triple DES system has been implemented on Virtex-E FPGA. The result proves that the reconfigurable triple DES easily realizes, holds less hardware resource, has higher security level. Weak keys and semiweak keys can also be used in this reconfigurable triple DES system.
