OASIS members and other interested stakeholders,
The OASIS Electronic Identity Credential Trust Elevation Methods (Trust Elevation) TC  members have recently approved a Committee Specification Draft (CSD) and submitted it for 30-day public review:
Authentication Step-Up Protocol and Metadata Version 1.0
Committee Specification Draft 01 / Public Review Draft 01
12 November 2015
Electronic Identity Credential Trust Elevation Methods are used to increase assurance in entity identification using authentication events and related entity information for the purpose of risk mitigation when making access control policy decisions.
The goals of this Fourth Deliverable are:
· To propose simple Trust Elevation architectural patterns demonstrating the use of Trust Elevation in modern Access Control architectures.
· To describe a common metadata set, mechanisms and protocol elements for Trust Elevation information exchanges.
· To promote the use of Trust Elevation elements to facilitate standardization among the many technologies and approaches currently in use for credential & authentication risk mitigation.
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.
