This paper consists of two parts, One is the ECC( GF(2/sup m/)) algorithm to improve the security strength and the processing time of SSL VPN and the other is the WLCAPT algorithm instead of LSNAT for the security strength of virtual server. In general when corporates use SSL protocol in order to build VPN, they use RSA algorithm with the problem of security and processing time about authentication and confidentiality, In this paper, a shared public key is generated with ECSPK which uses ECC( GF(2/sup m/)) algorithm to improve the security and processing time instead of RSA In addition, WLCAPT algorithm proposed in this paper is applied to virtual server which resides in the server side and then after NAT translation, the actual server of headquarter is securely communicated with it.
