Method and device for establishing a security mechanism for an air interface link
A method, a device, and a system for establishing a security mechanism for an air interface are provided in embodiments of the present invention. The method includes: performing security processing for a shared key of an access link according to a shared key between a relay node and a mobility management entity; and sending the shared key of the access link after the security processing to the relay node to enable the relay node to obtain the shared key of the access link based on the shared key between the relay node and the mobility management entity. The present invention reduces the possibility at which the air interface link is hacked, thereby improving the security of the air interface link.
