| A Scheme for the Session Key Exchange and Identity Authentication Based on Smart Card |
|
| () |
| Abstract: |
| Based on the security of the RSA and the discrete logarithm problem, a scheme for the session key management is presented which effectively combines session key exchange and identity authentication,and then the security of the scheme is analyzed in this paper. Smartcard Management Center(SMC) is responsible for distributing and managing smartcard. All of the users in the system use a Public Key of the SMC. Session Key exchange and identity authentication can be completed by the two parties of the communication independently without SMC or the Public Key Certificate of the opposite party. |
