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. ...
