| Abstract: | On the basis of RSA cryptosystem,a user authentication scheme for digital mobile communication networks is proposed,whose security is based on large integer factorization to resist several kinds of attacks including inside-attacks.Pre-calculation was used in user ends to reduce the realtime calculation and make the scheme satisfy real-time requirement of mobile communication system.Compared with the scheme based on DLP,the scheme reduces the computation and storage both in the user ends and the net center,which makes sequential requests more efficient.Analytical results show that the scheme can meet the requirements of mobile communication because of its high security,lower calculative complexity and less storage demands. |
