A provably secure coercion-resistant e-voting scheme with confidentiality, anonymity, unforgeability, and CAI verifiability [PDF]
PLoS ONEEnsuring both cast-as-intended (CAI) verifiability and coercion-resistance in e-voting remains a critical challenge. The e-voting scheme proposed by Finogina and Herranz in 2023 represents the first notable advancement in reconciling these conflicting ...

Quantum Physical Unclonable Functions: Possibilities and Impossibilities [PDF]
Quantum, 2021 A Physical Unclonable Function (PUF) is a device with unique behaviour that is hard to clone hence providing a secure fingerprint. A variety of PUF structures and PUF-based applications have been explored theoretically as well as being implemented in ...

Logarithmic-Size Post-Quantum Linkable Ring Signatures Based on Aggregation Operations [PDF]
EntropyLinkable ring signatures are a type of ring signature scheme that can protect the anonymity of signers while allowing the public to verify whether the same signer has signed the same message multiple times.

Group signature with time-bound keys and unforgeability of expiry time for smart cities
Eurasip Journal on Wireless Communications and Networking, 2021 Internet of Things (IoT) lays the foundation for the various applications in smart cities, yet resource-constrained IoT devices are prone to suffer from devastating cyberattacks and privacy leak threats, thus are inevitability supposed as the weakest ...

Digital signature schemes with strong existential unforgeability [version 1; peer review: 2 approved] [PDF]
F1000Research, 2021 Digital signature schemes (DSS) are ubiquitously used for public authentication in the infrastructure of the internet, in addition to their use as a cryptographic tool to construct even more sophisticated schemes such as those that are identity-based ...

Certificateless Signature with Strong Unforgeability in the Standard Model
Informatica, 2015 Certificateless public-key systems (CL-PKS) were introduced to simultaneously solve two critical problems in public-key systems. One is the key escrow problem in ID-based public-key systems and the other is to eliminate the presence of certificates in conventional public-key systems.

Forward Secure Lattice-Based Sequential Aggregate Signature Schemes in Stan-dard Model
Jisuanji kexue yu tansuo, 2021 In the forward secure sequential aggregate (FssAgg) signature scheme, the signer combines signatures generated in different intervals under different secret keys incrementally and sequentially in a layered “onion-like” fashion with the first signature ...

Forward Secure Sequential Aggregate Signature Schemes on Lattice
Jisuanji kexue yu tansuo, 2021 The forward secure sequential aggregate (Fss-Agg) signature has the advantages of forward secure signature and the sequential aggregate signature at the same time. Since its proposal in 2007, it has been widely applied in many application scenarios, such
