Abstract
A data security device for providing a network transport connection via a transparent network proxy that employs different encryption security mediums along a communications session between two endpoints by emulating one of the endpoints at an intermediate node such that the communication session appears as an atomic, secure connection to the endpoints yet provides appropriate security over the end-to-end connection. A sender node sends a connection request to establish a secure communication session with an intended receiver node. A transparent proxy on an intermediate node receives the request and establishes the link employing an encryption mechanism. The transparent proxy establishes a second link with the intended receiver, and applies a second, less expensive encryption mechanism. The transparent proxy combines the two links to form the trusted, secure connection but incurring only the mitigated expense over the second link.
