Non-contact CPU card technology to the Chinese science and Technology Museum (1)

Technical background

Since February 2009 Mifare 1 card algorithm to solve a wide range of social media are concerned, the non-contact IC card security issues have become smart card industry different media is one of the hottest topics; the cracked Mifare 1 card chip security algorithms, is currently the world's most widely used non-contact IC card security algorithms! you can imagine, if the research results be malicious use, then most access control system will lose their relevance, and other applications of this technology for IC card, such as the University student campus card, business card, it will face a huge security risk.

National Ministry of industry and information technology but also in response to this event in the country issued a related document, ask around for Mifare 1 card usage for investigation and response.

M1 card crack the diagram shown in Figure 1. And adopts domestic proprietary CPU card and CPU card system can effectively address the current traditional logic based on Mifare 1 encryption card card system there are serious security risks. As shown in Figure 2.

User situation

China Science and Technology Museum is the only State-level comprehensive science and Technology Museum, is the implementation of revitalizing and talent strategy, improve the quality of national science popularization of large-scale infrastructure.

The first phase of the project in 1988 September 22 completion and opening up, phase to 29 April 2000, the new Museum opened in 2009, September 16, completion and opening up.

User requirements in the construction of full range of library card system, including anfangmen guard system, consumer systems, time and attendance system, Conference attendance system, visitor management, parking management, self-service system, etc.

For science and technology museum staff and visitors to the audience to provide intelligent card services, taking into account the M1 card there are serious security risks, user requirements are based on non-contact CPU card technology to build the whole Museum's corporate card system, using non-contact CPU card as identification, pay the carrier transactions.

System target

Tongfang corporate card system to present the world's most advanced non-contact CPU card technology as the core, with corporate LAN-based platform, using the popular network structure, communication patterns, and development tools to build.

Achieve enterprise "smart card" and "one card" function.

Tongfang series products

China Science and Technology Museum, the new Museum's employees use a single authorized CPU card, you can use a smart card system software functionality and hardware equipment for consumption, access control, time attendance, access integrated query, personnel and other "one cartoon" services; foreign audience through a CPU card, implementation in the enterprise's various, the system can also be extended to Conference attendance, health care, book lending, and other systems; more can and Enterprise HR system, OA system, financial system, building automatic control system, etc system connection, interaction and sharing data and information for business managers provide integrated query, a comprehensive analysis of the underlying data.
