Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] Aiming at the problem that there is currently no effective mechanism for fast authentication and data transmission of massive NB-IoT devices in the 5G network. The present invention greatly reduces the signaling overhead and communication overhead of access authentication and data transmission, and optimizes the NB-IoT device (IOTD i ) and the authentication and data transmission delay between the access and mobility management entity (AMF), to achieve fast and secure access authentication and data transmission between the NB-IoT device and the target AMF in the 5G network.

Abstract

The invention belongs to the technical field of communication network security, and discloses an anti-quantum rapid authentication and data transmission method for mass NB-IoT equipment. NB-IoT equipment with the same attribute or short distance forms an equipment group, and when the equipment group needs to access the network, each equipment calculates own signcryption by using a lattice homomorphic encryption algorithm; the signcryption is sent to the group leader GROUP LEADER. Then, all signatures of members in the GROUP LEADER aggregation group are signed, and the aggregation signatures are sent to an access and mobility management entity AMF; and after the aggregation signcryption is received, the AMF verifies the validity of the aggregation signcryption to determine the legality of the group of NB-IoT devices. According to the invention, access authentication and data transmission of a group of NB-IoT devices can be realized at the same time based on the homomorphic encryption technology of the cells without establishing a data bearer, so that the signaling flow is simplified. Compared with the prior art, the authentication and data transmission cost is lower.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a quantum-resistant fast authentication and data transmission method for massive NB-IoT devices. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the continuous development of mobile communication technology, the Third Generation Partnership Project (3GPP) has proposed standards related to the fifth generation mobile communication technology (5G), which marks the The official start of the evolution from the current long-term evolution system (LTE-A) to the next-generation mobile communication network 5G system. In the future 5G network, the Narrowband Internet of Things (NB-IoT) system has become an important branch of the Internet of Everything. The 3GPP committee proposed the core standards of the NB-IoT system. The emergence of these core standards enables each eligible I...
