Embodiment Construction

[0020] In order to facilitate a deep understanding of the technical content of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A network device authentication method provided by the present invention, the method includes:

[0022] Provide a smart card to a network device that needs to be authenticated, and the smart card includes at least a network device identity ID NE , the encryption key K shared with the CA center AC One or more of the information in ;

[0023] The network device generates a random number R and uses the encryption key K AC Encrypt the random number R to obtain the encrypted result E(K, R);

[0024] The network device sends the above encryption result E(K, R), the random number R, and the network device identity ID NE Send to CA center;

[0025] The CA center uses the encryption key K shared with the network equipment AC Decrypt the encrypte...

Abstract

A method for certifying network device includes providing intelligent card to network device, obtaining enciphered result E by network device, sending enciphered result and relevant data to CA center, distributing a communication cipher key to said network device by CA and informing new switched-in network device information of the other network device passed certification of CA by enciphering information with cipher key and informing relevant information of new switch-in network device to the other network device passed certification by CA center.

Description

technical field [0001] The invention relates to the security field of the telecommunication industry, in particular to the authentication technology of communication network equipment. Background technique [0002] In the telecommunications industry, in order to provide users with a safe and reliable communication environment, it is generally required that network devices that can see the user's security context are trusted. However, in the existing communication environment, there are situations where a network device that can see the user's security context believes that the network device is trusted without being authenticated by a reliable certification authority. For example, some network devices are deployed because they are It is believed to be authentic inside the carrier's computer room without authenticating it. In this way, such network equipment may be counterfeited, so when a user needs to communicate through such network equipment, there is a security risk. ...
