Problems solved by technology

[0007] (1) The structure of prior art 1 is less resistant to modeling attacks
[0008] (2) Blocks containing NVM in the structure of prior art 2 increase device resource overhead and are vulnerable to physical attacks
[0009] (3) Existing technologies 1 and 2 only support one-way authentication from server to device, and are vulnerable to spoofing attacks by fake servers, thereby destroying the entire authentication network

Embodiment Construction

[0044] The technical solutions in the embodiments of the invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments of the invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the invention.

[0045] The anti-modeling attack design based on LFSR-APUF proposed by the present invention is mainly divided into four parts: excitation generator, traditional APUF unit, LFSR unit, and control unit. Among them, the excitation generator mainly generates random excitation from the outside when it is implemented on the FPGA development board, and the external excitation generated by it is input into the LFSR unit and the control unit respectively. The control unit mainly controls the LFSR...

Abstract

The invention discloses a lightweight identity authentication protocol of an LFSR-APUF and a private Cover function, the lightweight identity authentication protocol is provided on the basis of an LFSR-APUF structure, a dynamic confusion scheme is realized, and a protocol model comprises a plurality of devices, a server and a database. The protocol has two parts of a registration stage and an authentication stage, the switching strategy of the LFSR unit changes along with the change of external excitation, dynamic time-varying fuzziness is realized through deep combination with the authentication protocol, and meanwhile, bidirectional authentication from equipment to a server and from the server to equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of information and communication, in particular to a lightweight identity authentication protocol of LFSR-APUF and a private Cover function. Background technique [0002] Based on existing and evolving information and communication technologies, the Internet of Things (IoT) connects and integrates the physical world and the digital space, and is generally considered to be a global network of uniquely addressable interconnected objects based on standard communication protocols. The internet. The Internet of Things is widely used in industrial control, environmental monitoring, warehousing and logistics, agricultural production, national defense and military, medical and health and other fields, and has gradually become one of the focuses of global scientific and technological development. However, with the continuous expansion of the scale of the Internet of Things, the number and types of access devices are...
