This 7th annual Symposium on Identity and Trust on the Internet brings together academia, government, and industry to explore all aspects of identity and trust. Previously known as the PKI R&D Workshop (2002-2007), our new name reflects interest in a broader set of tools and the goal of an identity layer for the Internet. We aim to get practitioners in different sectors together to apply the lessons of real-world deployments to the latest research and ideas on the horizon.
