PUDA – Privacy and Unforgeability for Data Aggregation [PDF]
, 2015 Existing work on secure data collection and secure aggregation is mainly focused on confidentiality issues. That is, ensuring that the untrusted Aggregator learns only the aggregation result without divulging individual data inputs. In this paper however we consider a malicious Aggregator which is not only interested in compromising users’ privacy but ...

Unforgeability of Blind Schnorr in the Limited Concurrency Setting [PDF]
IACR Communications in CryptologyBlind signature schemes enable a user to obtain a digital signature on a message from a signer without revealing the message itself. Among the most fundamental examples of such a scheme is blind Schnorr, but recent results show that it does not satisfy the standard notion of security against malicious users, One-More Unforgeability (OMUF), as it is ...

Analysis and improvement of an identity-based signature scheme from lattices [PDF]
Tongxin xuebao, 2015 Liu et al proposed an identity-based signature from lattices in 2013,and proved that it can achieve strong un-forgeability in the standard model.Through analysis,the security proof of this scheme has some defect,and then show that the scheme cannot prove

BUFFing signature schemes beyond unforgeability and the case of post-quantum signature [PDF]
, 2021 Modern digital signature schemes can provide more guarantees than the standard notion of(strong) unforgeability, such as offering security even in the presence of maliciously generated keys, or requiring to know a message to produce a signature for it ...

A Delegation Attack Method on Attribute-Based Signatures and Probable Solutions
Mathematics, 2022 Attribute-based signature (ABS) assures the verifier that the message is endorsed by a signer whose attributes satisfy the claimed attribute policy (predicate); thus, it can provide identity authentication with privacy preservation in scenarios like ...

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 ...
