Generic Constructions for Verifiably Encrypted Signatures without Random Oracles or NIZKs

Markus Rückert, Michael Schneider, Dominique Schröoder

Lecture Notes in Computer Science > Applied Cryptography and Network Security > Digital Signature > 69-86

Verifiably encrypted signature schemes (VES) allow a signer to encrypt his or her signature under the public key of a trusted third party, while maintaining public signature verifiability. With our work, we propose two generic constructions based on Merkle authentication trees that do not require non-interactive zero-knowledge proofs (NIZKs) for maintaining verifiability. Both are stateful and secure...

A Secure Round-Based Timestamping Scheme with Absolute Timestamps (Short Paper)

Duc-Phong Le, Alexis Bonnecaze, Alban Gabillon

Lecture Notes in Computer Science > Information Systems Security > Short Papers > 116-123

The aim of timestamping systems is to provide a proof-of-existence of a digital document at a given time. Such systems are important to ensure integrity and non-repudiation of digital data over time. Most of the existing timestamping schemes use the notions of round (a period of time) and round token (a single value aggregating the timestamping requests received during one round). Such schemes have...
