Electronic Identity Credential Trust Elevation Framework V1.0 published

OASIS is pleased to announce the approval and publication of a new Committee Specification by the members of the OASIS Electronic Identity Credential Trust Elevation Methods (Trust Elevation) TC:

Electronic Identity Credential Trust Elevation Framework Version 1.0
Committee Specification 01
22 May 2014


This specification recommends particular methods as satisfying defined degrees of assurance for elevating trust in an electronic identity credential, to assure the submitter's identity sufficiently to support elevation between each pair of assurance levels to transact business where material amounts of economic value or personally identifiable data are involved. Alternative and optional methods may be included. The description of each recommended method includes functional definitions of the types of identity and assertion data employed by each method, and may include specification of the data services required in each elevation, substantive data exchange patterns or models, message exchange patterns or models, and such other elements as the TC deems useful.

About the TC:

The OASIS Trust Elevation TC works to define a set of standardized protocols that service providers may use to elevate the trust in an electronic identity credential presented to them for authentication. The Trust Elevation TC is intended to respond to suggestions from the public sector, including the U.S. National Strategy for Trusted Identities in Cyberspace (NSTIC). The Trust Elevation TC promotes interoperability among multiple identity providers--and among multiple identity federations and frameworks--by facilitating clear communication about common and comparable operations to present, evaluate and apply identity [data/assertions] to sets of declared authorization levels.
