Problems solved by technology

[0003] (1) Each lane terminal must be equipped with a PSAM card, and a PSAM card needs to be added for each additional lane, which increases the cost of materials
[0004] (2) The PSAM card contains a key. If the PSAM card is lost, there will be a risk of leakage. Therefore, the more PSAM cards scattered in each lane, the higher the management risk and the higher the management cost.
[0005] (3) The PSAM card is installed offline at the lane terminal. When the key algorithm needs to be upgraded, only the PSAM card of each lane can be replaced, which is inconvenient to upgrade

Embodiment Construction

[0029] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0030] A kind of PSAM array encryption operation service method, such as figure 1 shown, including the following steps:

[0031] In one embodiment, the step of receiving the request further includes the step of sending the request. After the charging terminal reads the card data of the ETC card, the charging terminal sends the PSAM encryption operation service request to the charging background online.

[0032] To receive the request, the main thread in the billing background receives the PSAM encryption operation service request, and assigns sub-threads to process the PSAM encryption operation service request.

[0033] Verification request, the sub-...

Abstract

The invention provides a PSAM array encryption operation service method, including the steps of receiving a request, verifying a request, and dynamically calling resources; the invention relates to a PSAM array encryption operation service system, including a charging background, a PSAM array encryption operation service module, and a charging terminal The present invention also relates to a computer-readable storage medium; the present invention realizes that a PSAM card supports multiple toll terminals to read and write ETC cards by using limited PSAM card resources in an online dynamic calling mode, which saves material costs and realizes Efficient utilization of PSAM card resources, online access and unified management, the toll terminal does not need to provide a PSAM card slot, and communicates with the toll background through wireless communication, which simplifies the toll terminal equipment and solves the high management risk caused by PSAM cards scattered in the lane. For high cost, PSAM resources are deployed centrally in the charging background, which is convenient for centralized upgrade and replacement, and improves the flexibility of key upgrade.

Description

technical field [0001] The invention relates to the field of intelligent security technology, in particular to a PSAM array encryption operation service method, storage medium and system. Background technique [0002] During the charging process of the traditional manual semi-automatic toll collection system (MTC, Manual Toll Collection System) and electronic non-stop toll collection system (ETC, Electronic Toll Collection System), it is necessary to use a key to read and write the ETC card, and the key is inserted in the driveway. Provided by the PSAM card on the terminal device, usually a lane needs to be equipped with a PSAM card. The problems with this encryption method are: [0003] (1) Each lane terminal must be equipped with a PSAM card, and a PSAM card needs to be added for each additional lane, which increases the cost of materials. [0004] (2) The PSAM card contains a key. If the PSAM card is lost, there will be a risk of leakage. Therefore, the more PSAM cards s...
