2018/11/8
We introduce the forward secure signature scheme XMSS++ and present an implementation for smart cards. It is based on the hash-based signature scheme XMSS. In contrast to the only previous implementat...
Forward-Secure Signatures with Optimal Signing and Verifying
Forward-Secure Signatures Optimal Signing Verifying
2009/4/16
We propose the first forward-secure signature scheme for
which both signing and verifying are as efficient as for one of the most
efficient ordinary signature schemes (Guillou-Quisquater [GQ88]), ea...
In regular digital signatures, once the secret key is compromised, all signatures, even those
that were issued by the honest signer before the compromise, will not be trustworthy any more.

Forward-Secure Signatures with Untrusted Update
Forward-Secure Signatures Untrusted Update
2008/12/16
In most forward-secure signature constructions, a program that updates a user’s private signing key must have full access to the private key. Unfortunately, these schemes are incompatible with several...
