Embodiment Construction

[0073] The specific embodiments of the present invention will be further described and explained in detail below in conjunction with the drawings and specific embodiments.

[0074] Such as figure 1 As shown, a lightweight certificateless industrial Internet of Things access control method uses the local server as a trusted third party, using public key-based challenge responses, tokens and passwords to achieve mutual authentication between users and resource servers, and The communication key negotiation is integrated into the authentication process, which effectively reduces the number of interaction rounds in the authentication process while ensuring the security of user authentication and key negotiation.

[0075] The method is based on the following settings: the resource server RS ​​and the local central server LCS responsible for its authentication have preset the public key information of the other party, the resource server RS ​​presets the address information of the l...

Abstract

The invention discloses a lightweight certificateless industrial Internet of Things access control method and system. According to the method, a local central server responsible for authorization carries out identity authentication on two parties according to an OAuth thought; different from ACE-OAuth, traditional (such as certificate-based) communication key negotiation needs to be carried out before authentication. According to the method, a local server is used as a trusted third party; two-way authentication between a user and a resource server is realized by using challenge response basedon a public key, a token and a password; communication key negotiation is integrated into an authentication process; the resource server does not need to distribute, receive and verify certificates while the security is ensured; the number of interactive rounds in the authentication process can be effectively reduced, then the communication data transmission amount and the key negotiation calculation consumption including CPU occupation, disk occupation, memory occupation and the like are effectively reduced, and the method is more dominant in safety and practicability and is more suitable for resource-limited environments such as the industrial Internet of Things.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a lightweight certificateless industrial Internet of Things access control method and system. Background technique [0002] The "Internet of Everything" feature of the Internet of Things allows IoT devices that were originally isolated from the external network to be seamlessly integrated into the Internet infrastructure, which makes IoT devices vulnerable to attacks and abuse. How to optimize the security authentication and Access control of resource devices has become an urgent problem in the current security protection of the Internet of Things. However, traditional solutions, such as Radius authentication protocol, NAC authentication scheme, OpenID, etc., do not take into account the limited computing resources of IoT devices, making it difficult for them to meet the scalability, interoperability and portability of IoT systems. internal needs. [0003] In this...
