Abstract:
Embodiments disclose a method, an apparatus, and a system for establishing a security context and relates to the communications field, so as to comprehensively protect UE data. The method includes: acquiring an encryption algorithm of an access node; acquiring a root key and deriving, according to the root key and the encryption algorithm, an encryption key of the access node; sending the encryption key and the encryption algorithm to the access node, so that the access node starts downlink encryption and uplink decryption; sending the encryption algorithm of the access node to the UE so as to negotiate the encryption algorithm with the UE; and instructing the access node to start downlink encryption and uplink decryption and instructing, during algorithm negotiation, the UE to start downlink decryption and uplink encryption.

Claim (Index 11):
A system for establishing a security context, comprising:\n A base station; and a core network, the core network being configured to be connected to a user equipment (UE) through a first air interface of the base station and through a second air interface of an access node, the base station being configured to\n send a root key to the access node; \n acquire an encryption algorithm used by the access node; \n send the encryption algorithm of the access node to the UE so as to negotiate the encryption algorithm with the UE; \n instruct the access node to start downlink encryption and uplink decryption; and \n instruct the UE to start downlink decryption and uplink encryption; \n the access node is configured to\n receive the root key sent by the base station; select the encryption algorithm according to the security capability of the access node, the security policy of the access node, and the security capability of the UE; \n derive the encryption key according to the root key and the encryption algorithm; send the encryption algorithm to the base station, so that the base station negotiates the encryption algorithm with the UE; and \n start downlink encryption and uplink decryption according to a startup indication of the base station.
