Application Of Secure Chip In Authentication System

With the development of technology and changing lifestyles, authentication has gradually penetrated into people all aspects of life, almost everyone through a variety of authentication methods for network transactions.At the same time, it also becomes a important subject to countries because of its special relation with the safety of nation .So the technology of authentication is the important methods to protecting people's personal information, and it is already a great subject which many people take attention to. And at the same time, the appearance of secure chip supports lots of new technologies because the strong ability of protecting the data in a hardware way. And how to use them at the same time and at the same product is one of the most popular fields of research.The purpose of this project is to discuss how to use the secure chip in authentication system on the base of designing of one kind of cure chip. And we will also discuss about three projects based on it, including the mobile payment, secure SD card, and the testing system of secure chip. This secure chip has the MIPS core, which is one kind of RISC having the 5-stage pipeline. The mobile payment contains three parts: the SIM chip, secure chip, and RF module. The secure has the functions of authentication. And the RF module which spread the public frequency band of 2.4GHertz. We can achieve the function of pay our fee with mobile phones by designing the system with these three parts. The secure SD card also contains three parts: the SD controller, the secure chip and the flash module. The secure chip in it can encrypt data and authenticate. And we also can realize the function of encrypt data on the terminal device by designing the system with them. The principle of the testing platform is the high efficiency and the stability. The main idea of designing it is to control the test of the chips put like matrix by the row controlling chips. And the whole body of designing the system contains the system theory design, the hardware design, he software design and the final debugging work.
