Abstract

In present network applications the proof of identity is guarantied by trusted third parties - so called Certification Authorities also referred to as trust centers. Certification Authorities are themselves hierarchically organized. Although this concept is well proven for handling trust relationships between distributed parties, it suffers consequently from the drawback that it relies on the trust in one basic Certification Authority. There are decentralized concepts for distributed environments to provide measures of trust mainly developed in theory of social networks. In present these concepts are applied in economics, sociology and organizational science. It is not applied in the field of application of telecommunication networks. It is proposed to apply decentralized concepts to provide measures of trust in telecommunication networks. The following abstract describes an embodiment to achieve this.

Establishing Trust Relationships In Peer To Peer Networks

Idea: Dr. Heinrich Huber; AT-Wien

In present network applications the proof of identity is guarantied by trusted third parties - so called Certification Authorities also referred to as trust centers. Certification Authorities are themselves hierarchically organized. Although this concept is well proven for handling trust relationships between distributed parties, it suffers consequently from the drawback that it relies on the trust in one basic Certification Authority. There are decentralized concepts for distributed environments to provide measures of trust mainly developed in theory of social networks. In present these concepts are applied in economics, sociology and organizational science. It is not applied in the field of application of telecommunication networks.

It is proposed to apply decentralized concepts to provide measures of trust in telecommunication networks. The following abstract describes an embodiment to achieve this.

In an exemplary environment of a number of peers (or services) the peers either trust themselves or not. Where we assume a not established trust relationship as no trust. Then P(A,B) denotes whether "peer A" trusts "peer B" P(A,B)=1 or not P(A,B)=0. We can write the particular trust level V(i) of "peer i" as:

0

This is an eigenvalue problem and can be solved with standard mathematical methods like matrix solving, polynomial root finding, et...
