A Multi-Core Adaptable Automatic Workflow Testing System Design for Security Chip

本文分析了多芯模组化智能电表的应用给安全芯片业务场景测试带来的挑战和问题,分析了传统测试方法中存在的缺陷,提出了能适应多芯业务场景的自动化业务测试系统。此方法通过提取用例,对安全芯片的业务进行模块化设计,提取密钥场景和芯片指令等可变量参数,封装SPI,7816,645协议,模拟多芯场景的业务交互流程,实现了业务流程的模块化和自动化,大大的提升了安全芯片业务流程测试的效率。

This paper analyzes the challenges and problems for workflow testing for introducing the mul-ti-core energy meter, and the faults of traditional workflow testing of security chip, and proposes a multi-core adaptive automatic workflow testing for security chip. This method is based on user case extraction and the workflow modulization of security chip. It extracts the variables like key state and instructions, and encapsulates SPI, 7816, 645 protocol, to simulate the multi-core workflow. It realizes the workflow modulization and automation, and greatly improves the efficiency of the workflow test and regression test.
