Design Method of Encryption Chip Based on AES-128 Encryption Algorithm

The mobile computer cryptographic machine is one kind of mobile encryption device.It takes the AES encryption chip as the core module and uses USB interface for communication between it and PC.The design of AES encryption chip decides the performance of the mobile computer cryptographic machine immediately.This paper introduces the design method of AES encryption chip,including the architecture design,the design of interface module between AES encryption/decryption module and USB chip,and the design of AES encryption/decryption module.The AES encryption chip is implemented by the Altera's Cyclone series FPGA EP1C12Q240C8.
