Trust Negotiation Goal protect resources from unauthorized access New approach to establishing trust between strangers

Initial trust among nodes is not necessary No need for registration (or even registration automatically)

Use of credentials: online analogue to the paper credentials in real life

Negotiation according to policies Access control policies can be used in both sides (requester and

provider)

Delegation Trust Negotiation trust is established gradually

through an iterative exchange of digital credentials
