Access authentication method and system for communication equipment of electric power internet of things

Abstract

The invention provides a power internet of things communication equipment access authentication method, which comprises the following steps: after communication equipment is connected with an authentication server, an authentication request message is sent for recording equipment information to the authentication server; the authentication server judges whether the equipment information in the authentication request message is matched with communication equipment information stored in the authentication server; if yes, the next step is executed: the authentication server generates an asymmetric key pair and sends the asymmetric key pair to the communication equipment; the asymmetric key comprises a public key and a private key; the communication device generates an identification ciphertext and a key ciphertext by using the asymmetric key, and sends the generated identification ciphertext and key ciphertext to an authentication server; and the authentication server carries out decryption authentication on the identification ciphertext and the key ciphertext, the communication equipment passes the authentication under the condition that the decryption authentication is passed, and the authentication server sends an access acceptance response message to the communication equipment, otherwise, the authentication server sends an access denial response message to the communication equipment.

Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, to a method and system for access authentication of electric power Internet of Things communication equipment. Background technique [0002] With the continuous development of power technology, the degree of automation and intelligence of related power equipment is getting higher and higher. By adding corresponding network access nodes, devices with different transmission protocols can achieve heterogeneous integration on the cloud and platform. It is not difficult to realize, that is, the Internet of Things that is often said in the industry. [0003] However, when the existing Internet of Things is connected to communication devices, it is directly connected by means of interface communication, and the platform lacks corresponding authentication operations, which increases the system security risk caused by network security issues.
