Embodiment Construction

[0074] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0075] In the prior art, the use environment of the PSAM card is an offline environment, and the use of the PSAM card has brought some risks because it is not restricted, such as the inability to monitor the PSAM card online, and the plug and play of the PSAM card has no requirements for the use environment and Lost PSAM cards cannot be invalidated in time, resulting in security management loopholes and so on. However, if the PSAM card is authorized and authen...

Abstract

The invention provides a PSAM card two-stage online authorization authentication method, device and system. The method comprises the following steps: judging whether a PSAM card is in a sign-in grey list issued by a management end according to a PSAM card authentication request sent by a lane charging end; if not, inquiring the number of remaining authorizable times from the counter; when the number of remaining authorizable times is not lower than a preset value, generating authentication key data for the PSAM card and returning the authentication key data to the lane charging end so that the lane charging end uses the authentication key data to authenticate the PSAM card; and receiving authentication success information returned by the lane charging end, and subtracting 1 from the number of authorizable times of the PSAM card in the counter. According to the invention, a plurality of response paths are expanded for the PSAM authorization request sent by the lane charging system, the authorization request sent by the lane charging system can be responded in time no matter whether the network is normal or not, and the availability and network anomaly resistance of the system are improved.

Description

technical field [0001] This application belongs to the technical field of ETC engineering, and specifically relates to a method, device and system for PSAM card double-level online authorization authentication. Background technique [0002] In order to ensure the rapid passage of expressways, PSAM cards are currently used as media to store transaction keys in the lane toll system. When a car enters or exits the highway entrance, the ETC user card held only needs to interact with the PSAM card of the lane toll collection system to complete functions such as information update and toll deduction transactions, without network communication with the outside world. [0003] Therefore, the existing expressway lane toll collection system only deploys a toll industrial computer and a card reader, and the card reader is provided with a PSAM card. When the expressway owner needs to open a new toll road section, he needs to apply for a new PSAM card to the superior key management unit...
