The research about WSN is not only mitted to its application, but also need to consider negative impacts brought by the plex application environments, the development of the work will inevitably face the corresponding security threats, so we must aim for adding security mechanisms to ensure the normal operation of the work. The ―Information Technology Sensor Network Information Security General Technical Specifications‖ from the perspective of security threats, puts forward the suitable security functions for sensor work and divides the work security into different level. The security technology in the Specification is widely used in sensor work, but there is no method to validates whether the implementation of the security functions have achieved the desired security objectives, or the means of implementation have been consistent with the specification, therefore, in this paper we research a kind of security testing technology which is suitable for wireless sensor work and set up a testing system to verify whether the implementation of the security functions meet the expected requirements and conform with the requirements of protocol conformance. The proposed security testing program of WSN is implemented based on the Web server, the main contents are as follows: Analyzes the characteristics of the WSN and the security testing requirements to develop safety test system objectives, including distributed management, the generation of test cases, the automatic execution of test cases, the printing of safety test report and the evaluation of safety level. Describes the principles of security testing methods, develops and designs security testing abstract set which is suitable for WSN through analyzing a formalized description of abstract test set and the structure analysis as well as security mechanism in sensor work security model. Deeply understanding of ―Information Technology Sensor Network Information Security General Technical Specifications‖, this paper designed a sensor work security testing system which is suitable for WSN and developed the security testing process. Moreover, security testing system proposed in this paper is implemented based on the test agent, so it has made a detailed plan for design and process of test agent. III Building security test platform based on the Web server to implement security testing system of WSN. The typical test case of this article is running in the selfdeveloped WIAPA protocol stack conducted by laboratory. Testing results show that this system can test whether the implementation of the security functions meet the expected goals, at the end of the test, according to test results the security levels of the test system can clearly be demarcate, Moreover, this testing system have guiding significance for the security testing of the sensor work.
