Abstract: In recent years, people have paid more and more attention to information security. The Internet of vehicles industry has developed rapidly. There are events called for by information security loopholes in the automobile market, causing significant economic losses and brand image damage. Automotive open system architecture has defined a component called secure onboard communication (SecOC), which introduces a set of communication encryption and verification standards for the on-board communication bus to protect the network communication between electronic control units in the vehicle. It can be said that SecOC is an effective information security scheme on the on-board network so far. SecOC test is mainly to test the function and performance of relevant components with SecOC module to verify whether the SecOC function of relevant components meets the requirements of SecOC network security design requirements. The SecOC automated test implementation scheme described in this article can automatically identify the changes in the requirements of the communication matrix according to the business needs, and testers do not need to update the test cases and related test scripts. The test script is written in CAPL, a C-like language developed by Vector company. Because it is widely used in the development of automotive electronics, it provides great convenience for the maintenance of the later test script. After the automated test of SecOC protocol is applied, the test system runs stably, the test time is shortened, and the tester can pay more attention to the software quality, thus greatly improving the test efficiency of SecOC protocol.
