Incremental Unforgeable Encryption [PDF]

open access: yes, 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 ...

An Identity-Based Anti-Quantum Privacy-Preserving Blind Authentication in Wireless Sensor Networks

open access: yesSensors, 2018
With the development of wireless sensor networks, IoT devices are crucial for the Smart City; these devices change people’s lives such as e-payment and e-voting systems. However, in these two systems, the state-of-art authentication protocols based

Adaptor signature scheme based on ISRSAC digital signature algorithm

open access: yesTongxin 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

open access: yesIEEE 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 ...

Quantum-secure message authentication via blind-unforgeability

open access: yes, 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 ...

BUFFing signature schemes beyond unforgeability and the case of post-quantum signatures [PDF]

open access: yes, 2023
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 ...

Two-Round Multi-Signatures from Okamoto Signatures

open access: yesMathematics, 2023
Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain

Mutual Heterogeneous Signcryption Schemes for 5G Network Slicings

open access: yesIEEE Access, 2018
With the emergence of mobile communication technologies, we are entering the fifth generation (5G) mobile communication system era. Various application scenarios will arise in the 5G era to meet the different service requirements.

Unforgeable noise-tolerant quantum tokens [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
The realization of devices that harness the laws of quantum mechanics represents an exciting challenge at the interface of modern technology and fundamental science. An exemplary paragon of the power of such quantum primitives is the concept of “quantum money” [Wiesner S (1983) ACM SIGACT News 15:78–88].
