Abstract

The invention discloses a method and a device for determining a key pair and a data processing method. The method for determining the key pair comprises: a key pair index value generating step of generating a key pair index value according to a preset key pair index initial value, a scrambling value and an ID or multicast / broadcast ID of equipment performing data communication; a key pair data determining step of determining required key pair data in a secure storage area according to the key pair index value; and a key pair determining step of decrypting the key pair data with a preset high-level key to obtain a required key pair. Through adoption of the method for determining the key pair, an encryption key can be appointed by a data receiving party and a data transmitting party without key management entities such as KTC / KDC, so that encryption transmission of voice and data information is realized, and the problem of information leakage in a current wireless communication process is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for determining a key pair, and a data processing method. Background technique [0002] With the rapid development of the mobile communication industry, mobile phones are not only widely used in personal life, but also play an increasingly important role in many fields such as government affairs and business activities. However, there are some hidden dangers in the existing mobile communication network, which lead to frequent occurrence of wireless eavesdropping and other incidents. For example, the GSM system, which is the mainstream standard of mobile communication, only supports air interface encryption and cannot provide end-to-end secure encrypted communication. Taking advantage of this feature of the GSM system, criminals can use equipment such as pseudo base stations to eavesdrop on voice and steal data. [0003] For this reason, releva...
