Cryptographic Protocol to Establish Trusted History of Interactions

In the context of ambient networks, this article describes a cryptographic protocol called Common History Extraction (CHE) protocol implementing a trust management framework. All the nodes are supposed to share the same cryptographic algorithms and protocols. An entity called imprinting station provides them with two pairs of public/private keys derived from their identities. Also, two strange nodes wanting to initiate an interaction have to build a seed of trust. The trust between two nodes is based on a mutual proof of previous common met nodes.
