Abstract

The invention discloses a method for realizing network access authentication, the key of which is that in the access request sent by the access device to the network access authentication device, the encryption public key pair of the anonymous qualification certificate and the access The information encrypted together with the identity of the access device, and the zero-knowledge proof information proving the legality of the anonymous qualification certificate; the network access authentication device confirms that the anonymous qualification certificate applied by the access device has not been revoked according to the received information, and verifies After the zero-knowledge proof is correct, the access device is considered legal and the access device is allowed to access the network. Applying the present invention, the network access authentication device can confirm the legitimacy of the access device without knowing the real identity of the access device. In this way, it not only ensures the security of the device accessing the network, but also hides the identity of the access device. identity of. Therefore, the access device is anonymous and unconnectable, which meets the user's requirements.

Description

technical field

[0001] The invention relates to the technical field of network access authentication, in particular to a method for realizing network access authentication. Background technique

[0002] At present, the network access authentication device performs authentication processing on devices to be connected to the network mainly based on the following technical protocols:

[0003] (1) Password authentication protocol;

[0004] (2) Based on the shared key and challenge response protocol;

[0005] (3) Based on the dynamic one-time password protocol;

[0006] (4) Authentication protocol based on public key system.

[0007] The idea of ​​all the above authentication processing is: network access authentication devices, such as firewalls, routers, authentication servers, etc., determine whether the access is allowed by judging whether the device to be accessed has the password and / or key required by the authentication protocol Device access. Applying the above acces...

Examples

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] There are certificate issuing entities, certificate revocation entities, access devices and network access authentication devices in the network. Among them, the certificate issuing entity has an issuing module responsible for issuing anonymous qualification certificates to legal access devices; the certificate revocation entity has a revocation module for revoking the legal qualification of access devices; A certification module used to prove the legality of the self-identity; a verification module used to verify whether the access device is legal exists in the network access authentication device used to verify the legality of the access device. The above-mentioned certificate issuing entity and certificate revocation entity may be the same physical entity or different physical entities.
