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 ...

Group signature with time-bound keys and unforgeability of expiry time for smart cities [PDF]
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 ...

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

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.

Strongly Unforgeable and Efficient Proxy Signature Scheme with Fast Revocation Secure in the Standard Model [PDF]
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 ...

Making Existential-Unforgeable Signatures Strongly Unforgeable in the Quantum Random-Oracle Model [PDF]
, 2015 Strongly unforgeable signature schemes provide a more stringent security guarantee than the standard existential unforgeability. It requires that not only forging a signature on a new message is hard, it is infeasible as well to produce a new signature ...

A Strongly Unforgeable Certificateless Signature Scheme and Its Application in IoT Environments [PDF]
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 ...

Unforgeable Quantum Encryption [PDF]
, 2018 We study the problem of encrypting and authenticating quantum data in the presence of adversaries making adaptive chosen plaintext and chosen ciphertext queries. Classically, security games use string copying and comparison to detect adversarial cheating

Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model [PDF]
Journal of Applied Mathematics, 2014 In a ring signature scheme, a user selects an arbitrary ring to be able to sign a message on behalf of the ring without revealing the signer’s identity. Whistle-blowers especially find this useful.

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 ...
