Ring signatures without random oracles
Since the formalization of ring signature by Rivest, Shamir and Tauman in 2001, there are lots of variations appeared in the literature. Almost all of the variations rely on the ra...

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...

Leakage-Resilient Cryptography from the Inner-Product Extractor
We present a generic method to secure various widely-used cryptosystems against arbitrary side-channel leakage, as long as the leakage adheres three restrictions: first, it is bou...

Generalized Key-Evolving Signature Schemes or How to Foil an Armed Adversary
Key exposures, known or inconspicuous, are a real security threat. Recovery mechanisms from such exposures are required. For digital signatures such a recovery should ideally —an...

Improved Security for Linearly Homomorphic Signatures: A Generic Framework
ded abstract of this work will appear in Public Key Cryptography — PKC 2012. This is the full version. We propose a general framework that converts (ordinary) signature schemes ...
