Embodiment approach

[0047] see figure 1 , the present invention is an IC card access control terminal using a commercial SM7 / SM1 cryptographic module (SAM). MCU is its core component, adopts a 32-bit single-chip microcomputer system, has 512KFalsh / 64KRAM, and has a variety of multi-channel communication interfaces built in. The access control terminal program developed by Shanghai Integrated Communication Equipment Co., Ltd. manages each component of the access control terminal under the control of these programs. The memory in the MCU stores the running program and the latest batch of access control events and alarm information.

[0048] The cryptographic module with commercial cryptographic algorithm is the core of security control in the access control terminal. It contains the 128-bit SM7 block cipher algorithm and SM1 block cipher algorithm designated by the State Cryptography Administration, and stores the system root key. Under the management of MCU, it is responsible for completing SM1 ...

Abstract

The invention relates to an IC (Integrate Circuit) card access terminal which adopts a commercial cipher and is provided with a commercial SM (Smart Media)7 / SM1 cipher module. The IC card access terminal comprises an antenna, an RF (Radio-Frequency) interface, an MCU (Microprogrammed Control Unit), a cipher module with a commercial cipher algorithm, an access executing mechanism and a data interface connected with a background monitoring system, wherein the MCU is respectively connected with the RF interface, the cipher module, the access executing mechanism and the data interface for data interaction, and the RF interface is connected with the antenna and is in charge for RF communication between the MCU and the IC card. An operation method of the invention comprises the following steps of: (1) swiping a card on the induction antenna of the access terminal by a user; (2) carrying out SA (Social Accountability) authentification on the access terminal and the IC card under the matched control of the MCU and the SM7 / SM1 cipher module; (3) carrying out SB authentification; (4) authenticating user release information; (5) controlling access; and (6) reporting a legal access accident to the background monitoring system. The invention has a commercial cipher secured authentification mechanism and effectively ensures the security of important access.

Description

technical field [0001] The invention belongs to an IC card access control terminal, in particular to an IC card access control terminal adopting a commercial SM7 / SM1 password module (SAM) and an operation method thereof. Background technique [0002] In today's society, IC card access control terminals have been widely used and become an important technical means of portal security management. The most used at home and abroad is the MiFare logic card, or M1 card access control terminal. In October 2008, the technical details of M1 card cracking were announced at an international conference, making a large number of IC card access control systems using M1 cards an unsafe system, posing a huge threat to the security and confidentiality of all levels of the country. Therefore, there is an urgent need to provide an IC card access control system that adopts a security technology with my country's independent intellectual property rights. [0003] According to Article 2 of Chapte...
