Key-Insulated and Privacy-Preserving Signature Scheme with Publicly Derived Public Key, Revisited: Consistency, Outsider Strong Unforgeability, and Generic Construction [PDF]
Liu et al. (EuroS&P 2019) introduced Key-Insulated and Privacy-Preserving Signature Scheme with Publicly Derived Public Key (PDPKS) to enhance the security of stealth address and deterministic wallet. In this paper, we point out that the current security

Quantum-secure message authentication via blind-unforgeability [PDF]
, 2020 Formulating and designing authentication of classical messages in the presence of adversaries with quantum query access has been a longstanding challenge, as the familiar classical notions of unforgeability do not directly translate into meaningful ...

A Publicly Verifiable Leveled Fully Homomorphic Signcryption Scheme
IET Information Security, 2023 With the deepening of research, how to construct a fully homomorphic signcryption scheme based on standard assumptions is a problem that we need to solve. For this question, recently, Jin et al.

Anti-Quantum Lattice-Based Ring Signature Scheme and Applications in VANETs
Entropy, 2021 Message authentication is crucial because it encourages participants to accept countermeasures and further transmit messages to legitimate users in a network while maintaining the legitimacy of the identity of network members. An unauthorized user cannot

International Journal of Distributed Sensor Networks, 2021 Fog computing is viewed as an extended technique of cloud computing. In Internet of things–based collaborative fog computing systems, a fog node aggregating lots of data from Internet of things devices has to transmit the information to distributed cloud

A Strongly Unforgeable Certificateless Signature Scheme and Its Application in IoT Environments
Sensors, 2019 With the widespread application of the Internet of Things (IoT), ensuring communication security for IoT devices is of considerable importance. Since IoT data are vulnerable to eavesdropping, tampering, forgery, and other attacks during an open network ...

ID-based server-aided verification signature scheme with strong unforgeability
Tongxin xuebao, 2016 Most identity-based signature schemes in the standard model are existentially unforgeable,which cannot prevent adversaries from forging valid signatures on messages that have previously been signed.However,signature verification algorithms of ID-based ...

International Journal of Distributed Sensor Networks, 2016 The existing proxy signature schemes with the proxy revocation function are proven to be malleable and do not possess strong unforgeability. Motivated by these concerns, a new proxy signature scheme with fast revocation is proposed, and it can be proved ...

Privacy Protection of VANET Based on Traceable Ring Signature on Ideal Lattice
IEEE Access, 2020 With the development of the Vehicular Ad-Hoc Network (VANET), protecting user privacy while ensuring security has become an immense challenge. A ring signature has the characteristics of no manager and unconditional anonymity, which can substantially ...

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 ...
