[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 ...
