Abstract:
In one embodiment, a method for providing secure communications using a proxy is provided. The proxy negotiates with a client and a server to determine a session key to use with communications between the client and the proxy and between the proxy and the server. Encrypted data may then be received from the client at the proxy. The proxy can decrypt the encrypted data for processing using the session key. In one embodiment, the decrypted data is not altered. The proxy then sends the encrypted data that was received from the client to the server without re-encrypting the data that was decrypted. Because the proxy did not alter the data in its processing of the decrypted data and the same session key is used between communications for the proxy and the server, the encrypted data stream that was received from the client can be forwarded to the server.
