ADAPTIVE TRAFFIC ENCRYPTION FOR OPTICAL NETWORKS

摘要

A technique is provided for a transmitting optical network element with an encrypting entity. The transmitting optical network element has an interface for receiving key information from a key management entity, storage means for storing a public key received by the key management entity, and a key generation entity configured for generating a symmetric encryption key. The transmitting optical network element is adapted to encrypt a received payload to be transmitted to a receiving optical network element using the generated symmetric encryption key, encrypt the generated symmetric encryption key using the public key of the receiving optical network element, and transmit the encrypted payload and the encrypted symmetric encryption key via an optical network to the receiving optical network element.
