Charging method and charging device of terminal

Abstract

The invention provides a charging method and a charging device of a terminal. The method comprises the following steps: acquiring cost information of a terminal; encrypting the cost information by using a symmetric key determined in the bidirectional authentication process of the application and the terminal to obtain a cost ciphertext; generating signature data according to a private key of the management server; transforming the signature data according to the signature transformation strategy to obtain signature transformation data; sending a notification message to the terminal; wherein the notification message carries the expense ciphertext and the signature transformation data so as to indicate the terminal to decrypt the expense ciphertext and obtain signature data through reverse transformation of the signature transformation data, and the signature data is verified by applying a public key of the management server; and receiving a legal verification message fed back by the terminal, and charging the terminal according to the cost information. According to the invention, the safe and reasonable charging of the terminal is realized, and the network performance is perfected.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a terminal charging method and charging device. Background technique [0002] Existing mobile networks or Internet networks can provide end users with various services, such as real-time transmission services of high-definition video, specifically, high-definition video conferencing, video monitoring, remote training, intelligent monitoring and analysis, emergency command, video telephony , live broadcast, TV mail, information release and other dozens of video, voice, picture, text, communication, data and other services. [0003] The service provider needs to invest a lot of manpower and material resources to support the operation of the above services. Therefore, it is particularly important to ensure the safe and reasonable billing of the terminal. The security of related data in the process and the security and reasonable billing of terminals have not y...
