Testing device for operating system of security chip

Abstract

The invention discloses a testing device for a security chip operating system, which is constructed through Python language and comprises a PCSC communication interface layer, an algorithm library interface layer, a function instruction interface layer, a basic algorithm interface layer and a script writing and executing layer. And communication with the to-be-tested security chip is realized through the PCSC communication interface layer. And the algorithm library interface layer is used for packaging interfaces of various security algorithms applied by the to-be-tested security chip. And thefunction instruction interface layer is used for packaging a function instruction in an operating system of the to-be-tested security chip. And the basic algorithm interface layer is used for performing secondary combination and packaging on the interface of the algorithm library interface layer and newly adding an operation function. The script writing and executing layer is used for storing, executing and modifying test scripts, and the script writing and executing layer achieves testing by combining and calling the PCSC communication interface layer, the algorithm library interface layer,the function instruction interface layer and the basic algorithm interface layer. The testing device for the operating system of the security chip can effectively improve the writing and debugging speed of the testing script.

Description

Technical field [0001] The invention relates to the field of security chip testing, in particular to a security chip operating system testing device. Background technique [0002] Smart cards are also called IC cards. According to the different integrated circuits used in IC cards, it can be divided into memory cards, logic encryption cards, CPU cards and radio frequency cards. Because the CPU card integrates a microprocessor, a storage unit and a chip operating system COS (Chip Operating System), a complete computer system is formed. [0003] The operating system COS of the CPU card is the most important part of the chip to realize the main application functions. It is the key to the safe storage and access of important information such as data, files, and keys in the security chip. The application of the actual functions in the chip must rely on the normal realization of the COS function, so there must be targeted tests for the correct realization of the COS function to ensure ...

Problems solved by technology

[0005] Although traditional language programs have long-term development experience and are relatively proficient and handy in building test frameworks and developing test scripts, they have their own problems and limitations for the test tasks themselves.

If VC is a static language, you need to declare its data type before using any variable, and you need to write a very detailed implementation process before implementing the test function, that is to say, you need to complete many lines of code to achieve it. At the same time, for novices, It takes a relatively long time to get started, and it will be a big bottleneck when encountering compilation or linking problems; on the other hand, VC does not have a corresponding intuitive UI control interface, which is inconvenient during test execution

And VB has ready-made controls and modules in the UI control interface, but there are many problems in the VB software itself, such as the readability of the code, the script execution rate is relatively poor, and VB is a relatively outdated language software, the main The test methods are all done manually, and the test efficiency is relatively low
