We put forward a framework for the modular design and analysis of multi-party protocols. Our framework is called “GNUC” (with the recursive meaning “GNUC’s Not UC”), alr...
We present a model and protocol for anonymous credentials. Rather than using deterrents to ensure non-transferability, our model uses secure hardware with biometric authentication...
This paper introduces the XTR public key system. XTR is based on a new method to represent elements of a subgroup of a multiplicative group of a finite field. Application of XTR ...
This paper considers the problem of key agreement in a group setting with highly-dynamic group member population. A protocol suite, called CLIQUES, is developed by extending the w...
Typical protocols for password-based authentication assume a single server which stores all the information (e.g., the password) necessary to authenticate a user. Unfortunately, a...
