Authentication method, device, access equipment and controllable equipment of network equipment

Abstract

The invention provides a network device authentication method, a device, an access device and a controllable device. The network device authentication method includes that after the access device is connected with the controllable device which is authenticated successfully and is connected to a network, a port, connected with the access device, of the controllable device is arranged to a controlled port by the controllable device, a filtering rule of the controlled port is that all messages except for messages used for authentication are filtered and blocked, an authentication request frame is sent to the access device through the controlled port, and then the controllable device receives an authentication response frame sent by the access device, abstracts certificate information, carried by the authentication response frame, of the access device, and packs the certificate information in the authentication messages to send to an authentication server, and authentication of the certificate information of the access device by the authentication server is facilitated. The network device authentication method, the device, the access device and the controllable device can achieve authentication of an authority of a network device based on the port and then achieve authentication of all devices accessed in the network, and improves safety of the network.

Description

technical field [0001] The invention relates to information security technology, in particular to an authentication method and device for network equipment, access equipment and controllable equipment, and belongs to the field of communication technology. Background technique [0002] Public key infrastructure (Public Key Infrastructure; hereinafter referred to as: PKI) is a key management platform that follows established standards and can provide cryptographic services such as encryption and digital signatures and the necessary key and certificate management systems for all network applications. In other words, PKI is the infrastructure for providing security services established using public key theory and technology. The core technology of PKI revolves around the entire life cycle of digital certificate application, issuance, use and revocation. [0003] The above-mentioned digital certificate is issued by the certificate authority (CertificateAuthority; hereinafter ref...
