Abstract: A method for providing secure communication in a computer system or network is disclosed where two or more clients, connect by firewalls and/or network address translation devices where no direct connection is possible, communicate via a proxy communication server using secure message transmission protocols such as the Secure Socket layer (SSL). Public-Private Key Exchange and secured data transfer are brokered by the proxy communication server as if the two clients are connected via the network directly without the need of decrypting the data and protocol communication traffic. The method provides enhanced security as no encryption key is disclosed on the proxy side and no data is transmitted or stored on the proxy unencrypted and improved performance is achieved as no data encryption or decryption is required by the proxy, and reduces network management requirements.
