Research On The Fuzzing Test Technology Based On MAC Layer

With the rapid development of information technology, information network has become an important guarantee for the development of the society. The Internet has been an important carrier of the information network. In recent years the mobile Internet has appeared and become increasingly important. There is much sensitive information in the information network, including personal privacy and even state secrets. The software that provides network service is the first line of defense against the network threats, and its security becomes very important. So how to quickly and accurately find the vulnerability of the network service software before its release is the urgent need. However, the Fuzzing test technology with respect to network protocols still has some problems, for example, the low automatic degree of knowledge acquisition, the inefficiency for multi-fields test, and the evaluation problems.Based on these disadvantages, we research on the fuzzing test technology based on mac layer, and make some achievements as follows:1. According to the three main problems, we put forward (1) a protocol description format PRDF, which can be more effective to describe the protocol;(2) A protocol field relationship analysis algorithm RATM, which can optimize multi-fields field selection and accelerate the test;(3) A method of evaluation of agreement, which can be more comprehensive to evaluate the test results.2. Design a Fuzzing test framework based on the algorithm we put forward above, where the users need not write the protocol description document. The users can easily use it, and focus their contribution on the test instead of learning how to use the tools.
