 Skip is hybrid Key distribution protocol 
Simple Key Management for Internet Protocols (SKIP) is similar to SSL, except that it establishes a long-term key once, and then requires no prior communication in order to establish or exchange keys on a session-by-session basis.Therefore, no connection setup overhead exists and new keys values are not continually generated.SKIP uses the knowledge of its own secret key or private component and the destination's public component to calculate a unique key that can only be used between them.
