Abstract

The present invention provides for a host web server (210) to encrypt and transmit information to a mobile client (240) such that the decrypted clear information (220) at no time exists in a third party WAP server (230) used at an intermediate point in the transmission to the mobile client (240). This is done by the web server (210) providing two or three or more layers of encryption prior to the SSL level of encryption of the clear information (220). Therefore, when the WAP server (230) decrypts the SSL level of encryption and encrypts the result by the WTLS protocol, then no clear information (220) exists in the WAP Server (230).
