A New Approach to Constructing Digital Signature Schemes (Extended Paper)
digital signatures hash functions public-key cryptography
2019/6/10
A new hash-based, server-supported digital signature scheme was proposed recently. We decompose the concept into forward-resistant tags and a generic cryptographic time-stamping service. Based on the ...
Subliminal channels in post-quantum digital signature schemes
Subliminal channels post-quantum digital signatures
2019/5/29
We analyze the digital signatures schemes submitted to NIST's Post-Quantum Cryptography Standardization Project in search for subliminal channels.
We present a pairing-based signature scheme for use in blockchains that achieves substantial savings in bandwidth and storage requirements while providing strong security guarantees. Our signature sch...
