Collaborative Automated Trust Negotiation in Peer-to-Peer Systems

by Song Ye, Fillia Makedon, James Ford - in P2P ’04: Proceedings of the Fourth International Conference on Peer-to-Peer Computing (P2P’04 , 2004
"... The increasing popularity of peer-to-peer systems has promoted the development of new techniques to support various kinds of business transactions. However, users are reluctant to conduct high value transactions over P2P systems due to the inherent untrustworthiness of peers. In this paper, we inves ..."

investigate building trust through automated trust negotiation, which is orthogonal to existing reputation-based approaches. Trust negotiation makes it possible to prove a peer satisfies certain trust requirements imposed by the ongoing business. We also introduce locally trusted third parties, which we

Automated trust negotiation

by William H. Winsborough, Ninghui Li - In DARPA Information Survivability Conference and Exposition, volume I , 2000
"... Exchange of attribute credentials is a means to establish mutual trust between strangers wishing to share resources or conduct business transactions. Automated Trust Negotiation (ATN) is an approach to regulate the exchange of sensitive information during this process. It treats credentials as poten ..."

Interoperable Strategies in Automated Trust Negotiation

by Ting Yu, Marianne Winslett, Kent Seamons , 2001
"... Automated trust negotiation is an approach to establishing trust between strangers through the exchange of digital credentials and the use of access control policies that specify what combinations of credentials a stranger must disclose in order to gain access to each local service or credential. ..."

Supporting Structured Credentials and Sensitive Policies through Interoperable Strategies for Automated Trust Negotiation

by Ting Yu, Marianne Winslett, Kent E. Seamons - ACM TRANSACTIONS ON INFORMATION AND SYSTEM SECURITY , 2003
"... ... this paper we provide the formal underpinnings for that goal, by formalizing the concepts of negotiation protocols, strategies, and interoperation. We show how to model the information flow of a negotiation, for use in analyzing strategy interoperation. We also present two large sets of strategi ..."

Limiting the Disclosure of Access Control Policies during Automated Trust Negotiation

by Kent E. Seamons, Marianne Winslett, Kent E. Seamons Marianne Winslett, Ting Yu - In: Network and Distributed System Security Symp. (NDSS 2001). Internet , 2001
"... Automated trust negotiation is a new approach to establishing trust between strangers through the exchange of property-based digital credentials, and the use of mobile access control policies that specify what combinations of credentials a stranger must supply in order to gain access to each local s ..."

Visualization of Automated Trust Negotiation

by Danfeng Yao, Michael Shin , Roberto Tamassia, William H. Winsborough
"... We have designed an interactive visualization framework for the automated trust negotiation (ATN) protocol and we have implemented a prototype of the visualizer in Java.

Automated Trust Negotiation Models

by Andro Galinović
"... Abstract. For secure communication and access control in open networks mutual trust between entities is needed. Today’s trust mechanisms are based on identities and credential exchange, in which the user is required to decide which credential to submit. This represents a problem in evaluating the tr ..."

the trustworthiness of entities which are complete strangers. One solution is an automated trust negotiation system, which governs and controls credential exchange needed for trustworthy communications. Many models have been proposed, each bringing improvements but also raising additional security issues

AUTOMATED TRUST NEGOTIATION USING CRYPTOGRAPHIC CREDENTIALS

by Jiangtao Li, Ninghui Li, William H. Winsborough , 2005
"... In automated trust negotiation (ATN), two parties exchange digitally signed credentials that contain attribute information to establish trust and make access control decisions. Because the information in question is often sensitive, credentials are protected according to access control policies. In ..."
