One-Time Signatures Revisited: Have They Become Practical?
Dalit Naor and Amir Shenhav and Avishai Wool
Abstract:
One-time signatures have been known for more than two decades, and
have been studied mainly due to their theoretical value. Recent
works motivated us to examine the practical use of one-time
signatures in high-performance applications. In this paper we
describe FMTseq - a signature scheme that merges recent
improvements in hash tree traversal into Merkle's one-time signature
scheme. Implementation results show that the scheme provides a
signature speed of up to 35 times faster than a 2048-bit RSA
signature scheme, for about one million signatures, and a signature
size of only a few kilobytes. We provide an analysis of practical
parameter selection for the scheme, and improvements that can be
applied in more specific scenarios.
