Research, Design And Implementation Of Security Initialization Of Crypto Card Based On USB HOST

Cryptogram technology is the kernel technology of information security, which can implement almost all kinds of security attribute such as information authentication, integrity, confidentiality, and controllability. Cryptographic algorithm and key are the very important part of cryptogram technology. The goal of the security initialization of crypto card is to ensure key and cryptographic algorithm security in the process of initialization, and security initialization of crypto card is one of the important aspects about security of crypto card.The thesis researches deeply all kinds of methods on security initialization of crypto card from technical aspect, and analyzes the reason that reduces the grave loss on the lost sensitive data of the basis of technical factor according to the FIPS. m discussion of Embedded USB HOST design model, the security initialization model of crypto card is put forward aiming at problem and shortage in the process of initialization.On the basis of the model of the mentioned hereinbefore, independent and special physical route is founded through Nios CPU and USB controller which is to make data transfer from point to point come true. Implementation scheme of security initialization is designed and brought to success in the manufacture crypto card based on SOPC. Security overall process is taken into account in the scheme, which is not only provided with ID Authentication, but function of configuration to crypto chip and destroy of sensitive data. Software and hardware scheme of security initialization are designed and implemented in emphasis in the thesis, and the difficulty about firmware design is described in detail.In the thesis, experimental result proves that scheme of security initialization put forward is correct, and implemented system can ensure correctness in the process of initialization accord with system requirements.
