METHOD, APPARATUS AND SYSTEM FOR SECURE COMMUNICATION OF LOW-COST TERMINAL

摘要

Embodiments of the present invention provide a method for secure communication of a low-cost terminal, which solves a communication security problem in the low-cost terminal and on a network side. The method includes: selecting, by an access point, a ciphering algorithm and an integrity algorithm according to a security capability of the low-cost terminal after successful authentication and key negotiation between the low cost terminal and a mobility management entity, and acquiring a cipher key and an integrity key according to the ciphering algorithm and the integrity algorithm; sending, by the access point, a security mode command including the ciphering algorithm and the integrity algorithm to the low-cost terminal so that the low-cost terminal calculates the cipher key and the integrity key; and receiving, by the access point, a security mode complete response message sent by the low-cost terminal. Embodiments of the present invention apply to radio communication.
