Problems solved by technology

The current test method is to infer that the multi-application smart card is safe and usable by verifying the correctness of the function of each application by performing a functional test on each application on the card, but such a test is not a real sense of security. The test is not enough to prevent possible security attacks on smart card COS multi-applications in the future

Embodiment Construction

[0014] In order to have a more specific understanding of the technical content, characteristics and effects of the present invention, now in conjunction with the illustrated embodiment, the details are as follows:

[0015] see figure 2 As shown, the security testing method of smart card COS multi-application isolation in the embodiment of the present invention is mainly completed by performing file structure test, file management test, key management test, security management test and instruction management test on smart card multi-application COS Security testing for isolation between applications. In the following description, the "certain application" refers to any one of all the various applications. The "a certain file" refers to any one of all files.

[0016] Before the file structure test, first review the system design document of the smart card COS to verify whether the system design adopts the independent storage space design when the multi-application file struct...

Abstract

The invention discloses an intelligent card COS (chip operating system) multi-application isolation safety testing method which includes file structure testing, file management testing, secret key management testing, safety management testing and instruction management testing. Viewed from system design and system implementation, safety of file structures, file management, secret key management, safety management and instruction management of an intelligent card multi-application COS is detected, so that possible loopholes of the COS in the implementation process of multiple applications are decreased, and safety of the intelligent card COS is improved.

Description

technical field [0001] The invention relates to the test field of a smart card COS (Chip Operating System), in particular to a safety test method for smart card COS multi-application isolation. Background technique [0002] With the continuous improvement of smart card "one card multi-purpose" requirements in modern life, the trend of integrating multiple applications on one smart card is becoming more and more obvious, which requires card data and card application security to be relatively independent for different applications of. That is to say, the application data of each application must be stored in partitions, and each application performs exclusive access and processing of its own data. [0003] For the smart card COS multi-application test, it mainly focuses on the functional test of each application, that is, the test of whether each application can correctly realize its own function, and the security test, especially the security of multi-application isolation. ...
