ABSTRACT:
A method for realizing network access authentication, wherein a network access authentication device pre-storing a system integrity value of a device waiting to access and a correspondence between each device waiting to access and its system integrity value. When the device waiting to access needs to access the network, it acquires its current system integrity value, and sends the current system integrity value to the network access authentication device; the network access authentication device judges whether the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical or not, and in a case where the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical, it determines that the network access is authenticated. As such, the network access device could determine the real status of the device waiting to access, and ensure the device accessing to the network is really secure, thereby ensuring the security of the network.
