Abstract
The present invention relates to a network device and an authentication method thereof. When one network device is connected with another one, the two network devices may respectively receive and transfer an authentication reporting packet each other. Accordingly, the network devices may compare context of the received authentication reporting packet and a stored authentication type information, a digest information, and an authentication protocol information for determining whether process the following specific protocol packet according to the comparison result.
Claims20
A network device configured to connect another network device, comprising:
- a storing unit, for storing an authentication type information, a digest information and an authentication protocol information;
- a packet unit, for transmitting a first authentication report packet to the another network device, and receiving a second authentication report packet from the another network device;
- and
- a verification module, for obtaining the authentication type information, the digest information and the authentication protocol information from the storing unit, and then respectively writing the authentication type information, the digest information and the authentication protocol information into an authentication type information field, a digest information field and an authentication protocol information field when the network device configured to connect the another network device, and comparing information of the authentication type information field, the digest information field and the authentication protocol information field of the second authentication report packet with the authentication information, the authentication information and the authentication protocol information in the storing unit so as to determine whether process a specific protocol packet from the another network device.
An authentication method adapted for an authentication of an another network device of a second layer in OSI layers, which method comprising:
- generating a first authentication report packet according to a first authentication type information, a digest information and an authentication protocol information;
- writing an predetermined media access control address into a destination address field of the first authentication report packet;
- transmitting the authentication report packet to the another network device;
- obtaining a second authentication type information, a second digest information and a second authentication protocol information of a second authentication report packet when receiving an authentication report packet;
- respectively comparing the second authentication type information, the second digest information and the second authentication protocol information with the first authentication type information, the first digest information and the first authentication protocol;
- and
- determining whether the authentication of the another network device is success or failure according to the comparing result.
