Wei Xiao-gan · Information Security and Communications Privacy · 2014
Based on the study of SPI communication technology,a solution for terminal chip applied in interface communication is proposed,thus to solve the problem of inefficient interface communication between secure chip and MCU. This paper firstly discusses the functional requirements of terminal secure chip and the hardware platform for those functional requirements. Then it gives the specific design of software and hardware and the implementation of encryption algorithm via SPI communication. Test result and pilot project show that this design is of practical value and good effects.
