Abstract

The embodiment of the invention provides secret key notification and decryption method and device in generic bootstrapping architecture push (GBA Push). The secret key notification method comprises the steps of: encrypting push information to be pushed to user equipment (UE) respectively by using a first secret key and a second secret key so as to generate two encrypted push information; and sending the two encrypted push information and corresponding secret key type information thereof to the UE. Therefore, the problem that the UE cannot decrypt the push information during GBA Push due to the inconsistency between the secret key type pushed by a server and a secret key type supported by the UE is solved.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for key notification and decryption in a general bootstrapping framework push (GBA Push). Background technique [0002] In the third-generation wireless communication standard, GBA technology is a general framework used by various application business entities to complete the verification of user identities, and at the same time generate a shared key to protect application communication. GBA push is a technology used to meet the requirements when a network application server actively initiates an application to a user. [0003] GBA push can be divided into GBA push based on GBA mobile equipment (GBA_ME) and GBA push based on GBA card (GBA_U). Wherein, the user equipment (User Equipment, UE) includes a mobile equipment (Mobile Equipment, ME) and a universal integrated circuit card (Universal Integrated Circuit Card, UICC). [0004] In the case of GBA push...
