A method for realizing network access authentication, includes: the network access authentication device prestoring the system integrity value of the access device and the corresponding relation between each device waiting to access and the system integrity value. When the access device need to access the network, it takes the current system integrity itself, 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 the system integrity value stored by itself of the device waiting to access are identical, and in the case of the received current system integrity value of the device waiting to access and the system integrity value stored by itself of the device waiting to access being identical, it judges that the network access is authenticated. In this case, the network access device could determine the real state of the device waiting to access, and ensure the device accessing to the network is real secure, thereby ensure the security of the network. |
