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 ...

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 ...

Incremental Unforgeable Encryption [PDF]
, 2002 The recent selection of the AES block cipher to replace DES has generated interest in developing new modes of operation to supplement the modes defined as part of the DES standard [1,16,23]. We initiate the study of modes of encryption which are both incremental and unforgeable, and point out a number of applications for modes meeting these ...

Adaptor signature scheme based on ISRSAC digital signature algorithm
Tongxin xuebao, 2023 The adapter signature scheme can provide good properties of atomic exchange in the block chain, and has been widely used in practice.A new adapter signature scheme was constructed based on a digital signature algorithm for improved security of RSA ...

Medical Data Sharing Scheme Based on Attribute Cryptosystem and Blockchain Technology
IEEE Access, 2020 Electronic medical data have significant advantages over paper-based patient records when it comes to storage and retrieval. However, most existing medical data sharing schemes have security risks, such as being prone to data tampering and forgery, and ...

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 ...
