The Study and Application of Protocol Conformance Testing Based on TTCN-3

This paper is mainly focused on the TTCN-3-based protocol conformance test method and test system implementations. In this paper, based on the analysis of the SSL protocol software, and combined the architecture of TTCN-3 testing system, according to TTCN-3 Control Interface specification and SSL protocol software data structure characteristics, design and implement the SSL codec which used to implement the function of data conversion between abstract testing suit and actual network transmission in TTCN-3 testing system.
