Description

technical field [0001] The invention relates to a method in the technical field of information security, in particular to a cryptographic algorithm compliance detection system for a smart cryptographic key (USB Key) based on a security sandbox mechanism. Background technique [0002] With the implementation of the Gold Card Project in 1993, the application of the smart password key (USB Key) has gradually moved from exploration to standardization, and has been widely used in the fields of e-government, e-commerce, transportation, public security law enforcement, social security, taxation and health care. used widely. USB Key uses Universal Serial Bus (USB) interface technology, built-in single-chip microcomputer or smart card chip, has a certain storage space, can store the user's private key and digital certificate, and use the built-in cryptographic algorithm of USB Key to realize the encryption of business information and Authentication of user identity. The wide applic...

Problems solved by technology

In addition, the update of the test case database is generally carried out manually, and the update cycle is long

[0008] 2) The call interface is encapsulated, with low transparency

The traditional USB Key cryptographic algorithm detection platform only calls the interface provided by the manufacturer. This type of interface has been compiled into a dynamic or static link library by the manufacturer, and the internal implementation is opaque. The manufacturer may modify its interface to avoid the normal process of testing

[0009] 3) The test sample is small and does not meet the specifications of the State Cryptography Administration

Most of the existing test platforms are released earlier than the specification and cannot meet the standard

[0010] 4) The interface is simple and the operation is cumbersome

Most of the traditional USB Key cryptographic algorithm detection platforms use Microsoft Foundation Classes (MFC), or even only interactive consoles, with simple or no interface, poor sense of the times, cumbersome interaction, and complicated and unclear operation procedures. Difficulty in using

[0011] In view of the above-mentioned problems that the traditional smart password key takes a long time and is difficult to adapt to on-site evidence collection and on-site analysis, the smart password key cryptographic algorithm detection system based on the security sandbox mechanism developed by the present invention can quickly discover the cryptographic algorithm used by the smart password key, and On-site evidence collection, suitable for grassroots management departments to carry out on-site law enforcement
