Design of Parameter Transfer Method in Application Flow Test of Smart Energy Meter Security Chip

In this paper, aiming at the lack of universality of the parameter transfer method in the application flow test of the traditional smart energy meter security chip, a new parameter transfer method in the application flow of smart energy meter security chip is proposed. The dictionary technology is used in the unified test platform software to load, search, assign and transfer the variables in the test instruction set, and then the constants and variables in the instruction set are recombined to send the final test instructions to the smart energy meter security chip in the form of APDU instructions, which realizes the dynamic transfer of parameters in the application process of the smart energy meter security chip. At the same time, the automatic test function is realized, which not only improves the test efficiency but also reduces the development cost of test code.
