The Silent Circle Instant Message Protocol (SCIMP) is an encryption protocol that is no longer used , developed by Vincent Moscaritolo of the Swiss software company Silent Circle . The use of SCIMP enabled private conversations via instant messaging (IM) technologies such as XMPP (Jabber).

SCIMP offered encryption, perfect forward secrecy and authentication of the messages, as well as the secure exchange of shared secret keys .
