Abstract
A system and method for encrypting data communications between a client and server utilizes an untrusted proxy server to perform computationally expensive encryption calculations which would otherwise be performed by the client. Prior to transmitting the data message to the proxy server, the client masks the data message such that the data message is indecipherable to the untrusted proxy. The untrusted proxy performs the computationally expensive encryption calculations prior to transmitting the data message to the intended receiver.
