Problems solved by technology

[0005] According to the above, since the method of recharging the user card by using the security application library software and the random number generated by SAM can be controlled by the service processing terminal itself, therefore, the above-mentioned recharging method in the prior art may generate business Solve the problem that the terminal illegally recharges the user's card by itself

Embodiment Construction

[0025] An embodiment of the present invention provides a method for processing key information. The service processing terminal provides the first random number obtained by itself to the background processing system, and the background processing system uses the first encryption rule to perform an encryption operation on the first random number. Generate key information, and feed back the key information to the service processing terminal, and then the service processing terminal provides the key information to the SAM as the key information for authorization and authentication of the SAM, so that the user card is authenticated by the SAM Before recharging and other operations, the background processing system first authorizes and authenticates the legal identity of SAM, thereby ensuring that the service processing terminal uses SAM to recharge the user's card under the authorization and authentication of the background processing system, avoiding the use of existing The techni...

Abstract

The invention discloses a key information processing method and a device and a system thereof, which are applied in a smart card system and used for avoiding the problem that the charging mode in the prior art is possible to cause illegal self-charging on user cards by a business process terminal. The method comprises the steps of obtaining a first random number by a business process device; providing the obtained first random number for a background processing system; receiving key information which is fed back by the background processing system and generated by encryption algorithm on the first random number by using first encryption rules; and providing the key information which is used for authentication and authorization of a secure access module for the secure access module.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a key information processing method, device and system. Background technique [0002] "One-card system" is a system that needs to read and write the data in the user's card through the business processing terminal to realize business processing. Its definition can cover "bank one-card system", "municipal transportation one-card system" and so on. Through the "one card system", users can conveniently use the user card to perform card consumption, payment, recharge and other operations at the business processing terminal, and then the business processing terminal reports the operation results to the background processing system of the "one card system". [0003] like figure 1 As shown, it is a schematic diagram of the specific structure of the "one-card system" in the prior art. The system mainly includes three components: background processing system (including the background...
