Abstract

The invention discloses a security-sandbox-based USB key cryptographic algorithm detecting system. The security-sandbox-based USB key cryptographic algorithm detecting system comprises a USB key equipment hardware layer, a USB key equipment driving layer, a cryptographic algorithm interface layer, a cryptographic algorithm detection engine layer and a user interface layer. The USB key equipment hardware layer is used for supplying hardware support to the USB key equipment driving layer. The USB key equipment driving layer is used for supplying driving support to the cryptographic algorithm interface layer. The cryptographic algorithm interface layer is used for implementing a cryptographic algorithm computing function according to a test case. The cryptographic algorithm detection engine layer is used for generating test case data and analyzing computation results. The user interface layer is used for inputting detection parameters, outputting detection results and providing operation tips for a detector. The security-sandbox-based USB key cryptographic algorithm detecting system has the advantages of high stability, robustness and detection degree and the like, and the problems that a traditional detecting system is fixed in test case, long in consumed period and hard to adapt to scene evidence obtaining and crime scene analysis are solved.

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
