Research campus network platform of the safety in the identity authentication technology.This paper puts forward the key generation algorithm based on rapid identity authentication

the authentication way need only in the first time when the identification from the network platform service party

using an odd number of screening key theory reduced the identity authentication of calculation and improve the safety in the campus network platform identity authentication of the efficiency.Experimental results show that this algorithm can real-time the authentication of the operator

further ensure that the campus network as the safety of the platform.
