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 ...
