Trust

Here you can find some descriptions of trust. Depending of the trust model the authors explain some methods used for establishing trust in P2P applications. The document gives a survey of trust systems (policy based, reputation-based, social networks-based).

• A Survey of Trust Management and Resource Discovery Technologies in Peer-to-Peer Applications (Girish Suryanarayana, Richard N. Taylor)
  
  

The authors examine the issue of managing trust in P2P systems. They focus on reputation based schemes and give also a survey of related work.

• Managing Trust in Peer-to-Peer Systems Using Reputation-Based Techniques (Beng Chin Ooi, Chu Yee Liau, Kian-Lee Tau)
  
  

This paper presents an attribute vector calculus based approach for modeling a continuum of trust; which models the real world model of trust, as closely as possible.

• On trust for ubiquitous computing (N. Shankar and W. A. Arbaugh, 2002)
  
  

There is a conflict between trust and privacy. Both depend on knowledge about an entity. They work with multiple virtual identities and link evidences to an identity.

• Trading Privacy for Trust (Jean-Marc Seigneur, Christian Damsgaard Jensen)
  
  

Identity is a central element of computational trust. The lack of a central authority for all entities can be used for privacy protection.

• The role of identity in pervasive computational trust (Jean-Marc Seigneur, Christian Damsgaard Jensen)

• Trust Enhanced Ubiquitous Payment without Too Much Privacy Loss (Jean-Marc Seigneur, Christian Damsgaard Jensen)
