Group-based anonymous switching authentication method during machine-type communication

Abstract

The invention discloses a group-based anonymous switching authentication method during machine-type communication. By the aid of the group-based anonymous switching authentication method, the problem of congestion conditions due to the fact that large quantities of machine-type devices are switched over in existing standards mainly can be solved. The group-based anonymous switching authentication method includes procedures of enabling a current base station or current MME (mobile management entity) to transmit secure session information of all switched group members to a target base station or MME when first machine-type devices in machine-type communication device switched groups are about to be switched to the target base station from the current base station; allowing switching authentication procedures to be carried out between other machine-type devices in the switched groups and the target base station without MME contact, allowing the other machine-type devices to negotiate with the target base station eNB to obtain session keys so as to implement quick switching authentication of the devices in the groups. The group-based anonymous switching authentication method has the advantages that the signaling overhead can be greatly reduced under the condition that the privacy of users is guaranteed, and signaling conflict can be prevented.

Description

technical field [0001] The invention belongs to the technical field of mobile communication network security, and more specifically, the invention relates to a group-based anonymous handover authentication method in machine type communication. Background technique [0002] With the development of communication, Machine Type Communication (MTC) has become the driving force for mobile operators to develop a large number of real-time network applications. Machine Type Communication (MTC), also known as Machine-to-Machine (M2M), has drawn great attention from equipment manufacturers and research institutes in mobile networks. MTC is a special type of data communication. It is between one device and another entity over the internet or core network without any form of human intervention. Due to the characteristics of reduced deployment cost and better coverage of MTC, many new services and applications have emerged from the concept of MTC in our daily life, such as health care s...

AI Technical Summary

Problems solved by technology

The grouping method is suitable for LTE-A networks with a large number of mobile MTC devices. However, this method is only applied to the communication between MTCD and MTC server without considering the handover security under the current 3GPP standard

As far as we know, there is no relevant research on the handover authentication process of a large number of devices in the 3GPP network. The existing group-based access authentication methods in the LTE network still do not consider the mobile process of a large number of devices or are not applicable to LTE- A network
