Description
Technical field
What the present invention relates to is a kind of method of field of information security technology, the specifically cryptographic algorithm accordance detection system of a kind of intelligent code key based on security sandbox mechanism (USB Key).
Background technology
Along with the enforcement of Golden Card Program in 1993, the application of intelligent code key (USB Key), progressively from groping to move towards specification, obtains extensive utilization in fields such as E-Government, ecommerce, communications and transportation, police law execution, social security, tax tax revenue and hygiene medical treatments.USB Key uses USB (universal serial bus) (USB) interfacing, built-in single-chip microcomputer or intelligent card chip, there is certain storage space, private key and the digital certificate of user can be stored, utilize the built-in cryptographic algorithm of USB Key can realize the encryption to business information and the certification to user identity.The widespread use of USB Key facilitates intellectuality that business carries out, facilitation, modernization and safe, has greatly promoted social informatization process, has improve social operational paradigm, facilitated people's life.
For safeguarding commercial cipher industry development order, China reports commercial encryption product employing unification, the requirement of unified management, and has promulgated " Business Code Regulations " in October, 1999 by State Council.China " 12 " planning clearly proposes the thinking strengthening commercial encryption products innovation and management.Need for protecting the security of information assets of the close user of business, specification commercial encryption product market and state functionaries's supervision; forensics analysis must be carried out, so that have something to base on, in order controllable management to the production of the cipher type equipment such as intelligent code key, usage behavior.
The intelligent code key new product of various form, interface emerges in an endless stream in recent years, also all difference is very large for technical parameter, from various different intelligent cipher key and other USB storage device (USB flash disk etc.) cannot be distinguished in appearance, cause the predicament of product supervision.Product exists in a large number in the Misuse situation of market circulation and qualified products in violation of rules and regulations, therefore uses technology and the product of supervision aspect in the urgent need to intelligent code key, to strengthen forensics analysis dynamics, improves the efficiency of management and level.
Through finding the literature search of prior art:
In May, 2007, Password Management office of country has put into effect " intellective IC card and intelligent code key password inspection criterion " (trying), define intellective IC card and intelligent code key password Detection of content, test item, qualification determination criterion, and enforcement password detects the pre-processing requirements proposed intellective IC card and intelligent code key.Due to the time that the realization of most of detection platform is promulgated early than this specification, there is quite a few strictly not follow this specification, and have the following disadvantages in actual applications:
1) test case is fixed, and can predict Detection of content.The test case of tradition USB Key cryptographic algorithm detection platform has prestored in a database, and lawless person can obtain test case with comparalive ease, and underproof USB Key product only needs to add a small amount of code namely by test.In addition, the renewal in test case data storehouse is generally manually carry out, and the update cycle is long.
2) calling interface is packed, and transparency is low.Tradition USB Key cryptographic algorithm detection platform only calls the interface that manufacturer provides, and this class interface is compiled into dynamically or static link library by manufacturer, and inside realizes opaque, and manufacturer may modify to its interface, evades test normal flow.
3) test sample book is little, does not meet national Password Management office specification." intellective IC card and the intelligent code key password monitoring specification " of promulgating in May, 2007 clearly contains compliance test specification, conformance testing specifications etc. about symmetry algorithm, asymmetric arithmetic, hash algorithm.Existing most of test platform is promulgated early than specification, cannot be up to standard.
4) interface is simple and crude, complex operation.Tradition USB Key cryptographic algorithm detection platform uses Microsoft Foundation class libraries MFC (Microsoft Foundation Classes) mostly, even only has interactive console, interface is simple and crude or do not have interface, sense of the times is poor, loaded down with trivial details, operating process is complicated unintelligible alternately, brings the difficulty of use to basic unit testing staff.
The cycle is expended long for above-mentioned traditional intelligence cipher key, be difficult to the problem adapting to scene evidence taking, on-the site analysis, the intelligent code key cryptographic algorithm detection system based on security sandbox mechanism of the present invention's exploitation can find the cryptographic algorithm that intelligent code key uses fast, and carry out scene evidence taking, be applicable to lower management department and carry out on-site law-enforcing.
