Problems solved by technology

[0016] However, there are attackable methods in this scheme. Illegal terminals can cache the MIKEY message containing the service key update. After the SD card or embedded chip is powered on and initialized, the MIKEY message is sent to the UAM, so that the UAM can A valid service key is stored, but the operator has not implemented charging for the user. This is what the operator does not want to see, and this problem must be solved technically

Abstract

The invention provides a method, device and terminal for processing service keys, wherein the method comprises the following step: after intelligent storage equipment of a terminal is electrified, acquiring a current service key updating message sent by a service platform, wherein the current service key updating message comprises a service key and an identification for representing the validity of the service key; and determining that the service key updating message is discarded when the service key is stored in the intelligent storage equipment according to the identification for representing the validity of the service key. In the scheme provided by the invention, the risk that the service key is attacked when pluggable storage equipment is used for the television service of a mobile phone can be avoided.

Description

technical field [0001] The invention relates to the field of mobile TV systems, in particular to a method, device and terminal for processing service keys of mobile TV services. Background technique [0002] In the mobile TV system, a four-layer key system is used to ensure the viewing of encrypted radio and TV programs. The implementation device on the terminal side may be a (U)SIM (Subscriber Identity Module, customer identification module) card, a pluggable storage device (eg, Secure Digital Memory Card, secure digital SD card) or an embedded chip. The implementation devices on the terminal side may be collectively referred to as: User Authentication Module (User Authentication Module, UAM for short). [0003] Such as figure 1 As shown, it is the key management system of the existing mobile TV service: [0004] The UAM on the terminal side can share the user key on the network side and the terminal side by running the GBA (Generic Bootstrapping Architecture) boot proce...
