Abstract:

In order to prevent illegal copying of microcontroller software,this paper presents a MCU encryption and authentication system based on 1-Wire security device DS28E01-100.The principle and structural of the encryption and authentication system are described,and the MCU programming method of SHA-1 secure hash algorithm block and some functions,such as the writing secrets memory block,writing data memory page block and challenge-response authentication block,are given.The practical application indicates that the system can effectively improve the microcontroller software's capabilities to prevent illegal copying.

Key words: security device;MCU encryption and authentication;1-Wire;DS28E01-100
