European Workshop on Trust & Identity

In cooperation with GeantLogo184x80

Building interoperable global trust: bridging technology and policy divides


Extending trust amongst administrative domains quickly results in scalability challenge. Where a single organisation has managerial means to make for itself a risk assessment and then enforce measures to mitigate unacceptable risks, a distributed environment lacks such strong controls. Relations, be they contractual or based on consensus, can only alleviate concerns if all parties involved are clear in what assurance is provided, and relying parties can rest assured that they can build their risk assessment based on clearly identifiable standards. When building a trust infrastructure and PKI, the development of common baseline requirements has emerged as a scalable mechanism for global trust amongst large communities in both academia - in the form of the Interoperable Global Trust Federation IGTF - and beyond. In this talk we will explore the policy bridging model used by the IGTF, and how it compares to similar structures built for public trust and other implementation models like bridge PKIs based on policy mapping.
