Embodiment Construction

[0058] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0059] figure 1 It is a schematic flowchart of a group authentication method in an asynchronous group communication of an MTC device on an LTE network according to an embodiment of the present invention.

[0060] Such as figure 1 As shown, the group authentication method in the asynchronous group communication of LTE network machine type communication equipment provided by the present invention includes two stages of initialization and group authentication, the token needed for group authentication is generated in the initialization stage, and the initialization stage is used in the group authentication stage. Tokens distributed to group members perform group authentication for group members.

[0061] The initialization phase generates authentication tokens for group members as follows:

Abstract

Related technologies of the Internet-of-things are developed rapidly and widely applied. Machine type communication (MTC) can complete data information exchange and sharing between equipment without active participation of a user, has the characteristics of low cost, low power consumption and capability of transmitting information on a large scale, and is one of the most important communication modes in the Internet-of-things. Therefore, the security of the MTC needs to be emphasized, and the data security of the user needs to be protected. The invention provides a group authentication methodand a group authentication system in asynchronous group communication of machine type communication equipment in an LTE network, which construct a group authentication scheme by utilizing a (t, n) secret sharing scheme of Shamir, authenticate m (m is greater than or equal to t) machine type communication equipment (MTCD) at one time, and ensure the legality of MTCD identity of an access network. Meanwhile, in the token transmission process, an ElGamal encryption algorithm is used to ensure the security of the authentication token in the transmission process. By utilizing the method and the system, the group authentication can be completed only by one-time calculation, the confidentiality can reach the calculation security, and each group member only needs to carry one authentication token.

Description

technical field [0001] The present invention relates to the machine type communication device group authentication technology in the field of information security and the Internet of Things, in particular to a group authentication scheme based on Shamir polynomial and ElGamal encryption algorithm, more specifically, to a multi-device group authentication technology in an LTE network A method and system for generating token information and performing group authentication using Shamir's (t,n) secret sharing scheme in authentication. Background technique [0002] Machine Type Communication (MTC), also known as Machine-to-Machine Communication (M2M), can complete the exchange and sharing of data information between communication entities without the active participation of users. The characteristic of large-scale transmission of information is one of the important communication methods in the Internet of Things. [0003] LTE network is one of the 4G wireless mobile broadband co...
