A convenient way for securely storing sensitive data in a public storage area over a wireless network is disclosed. Data that is to be backed up is encrypted using a public key of the user and is sent over the wireless network using a Wireless Application Protocol (WAP) technique and preferably contained within the body of a SyncML document or an XML document. The encrypted data can be later retrieved using a WAP technique and decrypted using the private key of the user.

Secure wireless backup mechanism

A technique for improving throughput of a gateway interface includes: a client, e.g., a wireless client, forwarding a request to a server via the gateway; determining in the server whether the requested content has been validated, and if so, setting a predetermined header to &ldquo;validated&rdquo; and forwarding the requested content to the gateway, and if not, either setting the predetermined header to &ldquo;not validated&rdquo; or not setting the predetermined header, and forwarding the requested content to the gateway. The gateway determines whether the predetermined header of the forwarded content has been set to &ldquo;validated,&rdquo; and if so, forwards the requested content to the client after encoding the validated content, and if not, validates the content and then encodes the validated content and forwards it to the client. In this way, the gateway does not have to needlessly validate requested content which had already been validated.
