Abstract
It is an object of the present invention to provide a new technical solution of supporting special secure communication between user equipment which is located in an external network and an private network the user equipment belongs to. Specifically, transmitted data is encrypted/decrypted and authenticated by using pre-stored root keys corresponding to specific private networks and the agreed encryption/decryption and authentication algorithm at the user equipment and an access device. The manner of generating the encryption/decryption keys and authentication key is simplified, and the complexity of the access device at the private network end is reduced on the premise of not degrading the security grade. The technical solution of the present invention is highly flexible and extensible and can achieve better user experience.
