A Cryptographic Keys Transfer Protocol for Secure Communicating Systems

This paper describes a new key forwarding protocol for networks messages exchange which guaranties both authentication of participants and forward security. The protocol lies within the framework of a keys derivation scheme used for spanning tree-based networks messages diffusion where compromising a key in a node involves compromising all derived keys in the corresponding sub tree. A complete specification and full proof of the protocol will be subject of a longer forthcoming conjoint paper.
