Abstract

The invention discloses a data protection method, device and system in a communication system. The method includes: a core network node acquires service-related information of a terminal device; and the core network node determines a network node that performs security protection on data of the service according to the service-related information. The method can flexibly select different network nodes for different services to perform security protection, meet the security requirements of operators or services, and improve system security.

Description

technical field [0001] The invention relates to a communication system, in particular to a data protection method, device and system. Background technique [0002] In the Long Term Evolution (LTE for short) system, in order to ensure the security of data transmission, the base station (evolved node-B, eNB) performs security protection on the downlink data of the service of the terminal equipment, for example, encryption protection, integrity protection, and send the downlink data after the security protection to the terminal equipment through the air interface between the base station and the terminal equipment; sent to the base station. The securely protected data is in a secure state during air interface transmission, which can effectively prevent attackers from hijacking. [0003] However, with the evolution of 3GPP standards, the network structure and security requirements of communication systems are constantly changing. Therefore, data security protection needs to be...
