A Study on the Twofish Security Processor Design Using USB Interface Device
Since most cryptographic systems are PCI type, it is not suitable for users except experts to handle security system. In particular, most security programs used have not been verified against crack and are exposed to attack of virus or hacker. In this regard, this thesis designed Twofish cryptographic algorithm that uses USB, which can be easily used by users at general computers. Users can use security system easily using USB. In addition, Twofish cryptographic algorithm with various variable key lengths can be applied to various security system. Such Twofish cryptographic algorithm can improve performance for encryption and decryption, and increase efficiency of mobile security system in addition to USB.
