Method for carrying out security management on security element and communication system

Abstract

The invention relates to a method for carrying out security management on a security element and a communication system realized by employing the method. The method comprises the steps of loading a trusted application in a terminal device; establishing a security channel between the trusted application and a trusted service manager server; issuing a management key to the trusted application by the trusted service manager server through the security channel, and storing the management key by the trusted application; issuing a management instruction to the trusted application by the trusted service manager server through the security channel, and storing the management instruction by the trusted application; and carrying out content management on the security element by the trusted application based on the management key and the management instruction. According to the method and the system, on the basis of ensuring the data security, the networking times is reduced, and the performance efficiency of a take is improved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and a communication system for safety management of a safety unit. Background technique [0002] With the development of mobile communication technology, more and more applications can be integrated on the terminal. In order to implement these applications, the terminal sets some sensitive information, such as user information, in the security element (Se, SecurityElement) of the terminal. When sensitive information needs to be used, the application software of the terminal accesses the user information in the security element. The user information set in the security unit includes, for example, the user's personal information and account information. When accessing the security unit, any application software on the terminal can pass the application programming interface (OS) on the terminal operating system (OS, Operation System) API, Application Programming Interfa...

Problems solved by technology

However, there are also disadvantages, that is, it is necessary to communicate with the trusted service management server 10 in real time, and its error probability will be relatively high for terminal equipment whose network environment is not good enough, and may also cause the situation of sneaking traffic during silent processing, and at the same time When the terminal device has no network, content management will not be possible. For some applications with a slightly larger amount of data, the user experience cannot be smooth.
