Security
It is possible to encrypt information between client, gateway, and server, although support for this is not available from all clients and gateways. As described previously, WTLS provides encryption from client to gateway, and TLS between gateway and server. Due to this two-part encryption scheme, all data must be decrypted into plain text at the gateway prior to retransmission. This well-publicized security hole mandates that highly secure WAP services must use a dedicated WAP gateway, and it has also resulted in intense work on end-to-end encryption schemes.
