An instruction based automatic workflow testing method for security chip

This paper analyzes the faults of traditional workflow testing of security chip, and proposes a new automatic workflow testing for security chip. This method is based on instruction processing and encapsulates 645 protocol, to simulate the workflow of main station, security chip and electric energy meter. Comparing to traditional method, it overcomes the disadvantages that traditional workflow has no interactive testing with real energy meter which may lead to faults when testing on the real energy meter. Meanwhile, it advances the schedule of the smoke test and realizes the workflow modularization, greatly improves the efficiency of the workflow test and regression test.
