Provably Unforgeable Signatures [PDF]
, 2007 Very strong definitions of security for signature schemes have been proposed in the literature. Constructions for such schemes have been proposed, but so far they have only been of theoretical interest and have been considered far too inefficient for practical use.Here we present a new scheme that satisfies these strongest definitions and uses ...

Two-Round Multi-Signatures from Okamoto Signatures
Mathematics, 2023 Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain

Anonymous Single-Sign-On for n designated services with traceability [PDF]
, 2018 Anonymous Single-Sign-On authentication schemes have been proposed to allow users to access a service protected by a verifier without revealing their identity which has become more important due to the introduction of strong privacy regulations.

Fully leakage-resilient signatures revisited: Graceful degradation, noisy leakage, and construction in the bounded-retrieval model [PDF]
, 2016 We construct new leakage-resilient signature schemes. Our schemes remain unforgeable against an adversary leaking arbitrary (yet bounded) information on the entire state of the signer (sometimes known as fully leakage resilience), including the random ...

Oblivion: Mitigating Privacy Leaks by Controlling the Discoverability of Online Information [PDF]
, 2015 Search engines are the prevalently used tools to collect information about individuals on the Internet. Search results typically comprise a variety of sources that contain personal information -- either intentionally released by the person herself, or ...

Unforgiveness, rumination, and depressive symptoms among older adults [PDF]
Aging & Mental Health, 2010 The experience of feeling unforgiven for past transgressions may contribute to depressive symptoms in later life. This article tests a model in which feeling unforgiven by God and by other people have direct effects on depressive symptoms while self-unforgiveness and rumination mediate this relationship.
