基于Suite-B的密碼令牌接口系統(tǒng)的設(shè)計與實現(xiàn)
[Abstract]:With the increase of the security risk such as network attack and network trap, many countries, including our country, have promulgated the cipher algorithm suite for the respective countries, and the algorithm suite has its different protection range and protection information level. It may have been realized that the RSA algorithm has a security risk of being cracked, and the National Security Agency promulgated a suite of suite-B cipher algorithms that contain the ECC algorithm in 2009 and is put into use. In our country, because of the lack of application case and guidance specification of Suite-B algorithm suite in network security and data encryption, most network application systems still use the RSA algorithm-based algorithm suite, and the security risk is high. In this paper, the system implementation of Suite-B algorithm suite is applied in the field of network security, and the object-oriented method is put forward to analyze and design the token interface system. Firstly, this paper analyzes the requirement of the token interface system, and puts forward the function object that the system needs to realize, including token management, session management, etc. Secondly, in the process of system design, this paper completes the work of class design, key process design, etc. of the token object. the invention provides a foundation for system implementation; thirdly, a system implementation is carried out by using a C ++ language, wherein the password algorithm logic is provided by LibTomCrypto; and finally, the various functions of the interface system are verified through a test tool; and moreover, In this paper, the extensibility of the algorithm suite is realized by using the pure virtual technique and the derivation technique in the object-oriented method. The results of this paper show that the application of Suite-B algorithm suite can be realized through PKCS # 11. The research result of this project is a simple example of the application of Suite-B algorithm suite specification for application, and then provides the design and implementation of PKCS # 11 for other researchers.
