Cross-domain identity authentication method based on edge computing network architecture

Abstract

The invention discloses a cross-domain identity authentication method based on an edge computing network architecture, and mainly solves the technical problems that in the prior art, key management and distribution are difficult, and user privacy is difficult to protect. The method comprises the following steps: 1) an edge node local authentication server and a home authentication server calculaterespective public and private keys; 2) the home authentication server generates a private key constructed by the user by using the pseudo identity; 3) the user applies for cross-domain access to theedge node local authentication server; 4) the edge node local authentication server sends information to a home authentication server of the user to verify the identity of the user; 5) the home authentication server authenticates the user information and returns a session key; 6) the local authentication server of the edge node calculates the session key and returns the authentication information;7) the user confirms the information to generate the session key. According to the method, the bidirectional verification security of the edge node equipment and the user can be effectively improved,the problems that the identity privacy of the user is exposed and the session is tracked are solved, and the method can be used for modern Internet of Things equipment.

Description

technical field [0001] The invention belongs to the field of communication technology, relates to information security technology, and further relates to a cross-domain identity authentication method based on an edge computing network architecture. It can be used to securely authenticate edge device users in resource-constrained and complex edge networks, including mobile phones, Bluetooth watches, smart home and smart car devices. Background technique [0002] The edge in edge computing refers to any computing resource and network resource between the data source and the data path of the cloud computing center. The basic idea of ​​edge computing is to run computing tasks on computing resources close to the data source. For the current rapid development of the Internet of Things and 4G / 5G wireless networks, edge computing data processing at edge locations solves the explosive data growth processing load and reduces the congestion caused by the sharp increase in network tran...
