Abstract
Embodiments relate to routing encrypted data from a source to a sink via a router without decrypting the data in the router. The source authenticates with the router, the result of which produces a session key and a pseudo-random number. The router authenticates with the sink using the same session key and pseudo-random number. The router passes encrypted data received from the source to the sink without decryption and re-encryption.
