Towards Statistically Strong Source Anonymity for Sensor Networks
—For sensor networks deployed to monitor and report real events, event source anonymity is an attractive and critical security property, which unfortunately is also very difficu...

Pseudo-Voter Identity (PVID) Scheme for e-Voting Protocols
Voter anonymity, also known as unlinkability, is the primary requirement to satisfy privacy in e-voting protocols. Up until now, e-voting protocols have tried to make communicatio...

Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

How to Strengthen Any Weakly Unforgeable Signature into a Strongly Unforgeable Signature
Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...

Two-Tier Signatures, Strongly Unforgeable Signatures, and Fiat-Shamir Without Random Oracles
We provide a positive result about the Fiat-Shamir (FS) transform in the standard model, showing how to use it to convert threemove identification protocols into two-tier signatur...
