A public key infrastructure is generally (andeffectively) used for cryptographically secureauthentication in the networks. Ad-hoc networks areformed in haphazard manner. Security services for ad-hoc networks cannot assume the existence of aparticular infrastructure. Peer-to-peer technology ispromising in addressing security issues in ad-hocnetworks. We provide a novel; cryptographicallysecure representation of trust based on secure groups -troups. We show how troups can be constructed in adistributed manner using RSA accumulators. Thetroup-membership is verified using the zero-knowledgeprotocol of modular exponentiation. Each node in agroup has an identity within a group, but it is notrequired to reveal the identity during verification. Thistrust model is not centrally controlled and can bedeployed incrementally in the network. This paperpresents the protocols and a prototype implementationof the troups based authentication system.
