Abstract
Software has been developed very fast as information has become important value. Illegal software copy has been the main problem of developing software business. Recently used protecting lock system for software copy has not guaranteed perfectly from easily cracked-defense system. This paper, therefore, proposes 96-bit block cipher with 112-bit length to replace a DES(Data Encryption Standard) algorithm. Security chip by ASIC(Application Specific Integrated Circuit) security module is presented for software copy protection. Then, an auto block protecting algorithm is designed for the security chip. Finally, controlling driver and library are built for the security chip.
