Research of CRYPTO1 Algorithm Based on FPGA

摘要

The Mifare Classic card is the most widely used contactless smart card in the world. The internal encryption algorithm and security attract more and more people's attention recently. This paper studies three-pass authentication and gives the design procedure of CRYPTO1 algorithm. The design uses FSM method based on FPGA to implement this algorithm. Test results show that the system of encryption and authentication runs fast and correctly. The research builds the foundation to research and estimate the security of the smart card.
