Method and system for authorizing terminal equipment to print electronic bill

Abstract

The invention belongs to the technical field of terminal equipment communication, and discloses a method and system for authorizing terminal equipment to print an electronic bill. The method comprisesthe following steps: the terminal equipment sends encrypted registration message data to a background system for registration; the terminal equipment receives a result message for indicating a decryption result, analyzes the result message, and exits from a registration process upon a successful registration, which is represented by receipt of information that indicates a successful decryption; and when the successful registration is determined, the terminal equipment sends an authorization request to the background system, so that the background system can be prompted to authorize the terminal equipment to print the electronic bill according to the received authorization request. The method and system disclosed by the invention has the advantages that the method is simple and easy to implement, and redundant steps in the traditional control process are reduced; and the problems of CA certificate duplication or abusive use of authorization documents caused by the traditional method can be effectively avoided, and the problem of hash value leakage of self-service terminal equipment is solved, so that safe and effective data communication can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment communication, and more specifically, to a method and system for authorizing terminal equipment to print electronic bills. Background technique [0002] With the development of network technology, the popularity of terminal self-service machines is an inevitable trend. Whether the terminal self-service machine service can realize "24-hour self-service" can completely replace manual work to implement some repetitive and simple tasks. In addition, the popularization of terminal self-service machines can alleviate the heavy flow of people in the Chuangong business hall and make up for the lack of business hours. It is an extension and supplement of office services. [0003] The traditional connection control of hardware devices and background systems generally adopts methods such as controlling the machine number or authorization certificate of the connected device. This method h...

AI Technical Summary

Problems solved by technology

This method has certain application defects. For example, multiple hardware devices use the same device number or authorization certificate. In this case, the background system cannot correctly identify which hardware device or terminal is in the specific communication process. Self-service equipment

In addition, the method of controlling the connection between the hardware device and the background system is to authorize the CA certificate or realize the distribution of the device key. equipment, but the third-party authorized CA certificate can only be used after payment, and there is a certain number of years; in addition, using the key distribution method, the key is easily lost when the key is written into the configuration file, and the key may exist for many times. Therefore, this hardware control connection method also has certain application limitations
