Abstract

The invention discloses a vehicle entering/exiting control system and control method based on a semi-online key. The system comprises a PSAM (Purchase Secure Access Module) card, reading-writing equipment, a pass control system, a background management system and a key system, wherein the PSAM card is arranged inside the reading-writing equipment and electrically connected with the reading-writing equipment; the reading-writing equipment is electrically connected with the pass control system; the pass control system is connected with the background management system through a network; and the background management system is connected with the key system through the network. According to the control system, the PSAM card is arranged in the reading-writing equipment and combined with the background management system and the key system, and authentication and authorization are finished through communication interaction among the PSAM card, the background management system and the key system, so that the problem of dependence on the network quality is solved; the problem that the PSAM card is stolen and used maliciously is solved; and a balance point between the network demand and safety is found.

Description

technical field [0001] The invention relates to a vehicle access control system and control method based on a semi-online key. Background technique [0002] The vehicle access control system often needs to read and write the access credentials such as the CPU card or electronic tag of the vehicle. In order to complete this operation, relevant key calculations are required. Currently, key calculation methods mainly include an offline key method and an online key method. [0003] Among them, in the offline key mode, by installing a PSAM card in the read-write device, the PSAM card completes the key calculation and returns the calculation result. This method has the characteristics of fast calculation response speed and is not affected by the network. However, since each entrance and exit needs to be equipped with a PSAM card, and all security operations are completed on the PSAM card, there are risks such as PSAM card loss and malicious use. [0004] In the online key mode...
