Automatic Generation of Sigma-Protocols
Efficient zero-knowledge proofs of knowledge (ZK-PoK) are basic building blocks of many cryptographic applications such as identification schemes, group signatures, and secure mult...

Safety and consistency in policy-based authorization systems
In trust negotiation and other distributed proving systems, networked entities cooperate to form proofs that are justified by collections of certified attributes. These attributes...

A model and architecture for pseudo-random generation with applications to /dev/random
We present a formal model and a simple architecture for robust pseudorandom generation that ensures resilience in the face of an observer with partial knowledge/control of the gen...

Integrity (I) Codes: Message Integrity Protection and Authentication Over Insecure Channels
Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bi...

The Fiat-Shamir Transform for Group and Ring Signature Schemes
The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...
