Digital Signature Based on Quantum Key Exchange Algorithm [PDF]

open access: yesEngineering and Technology Journal, 2015
Digital signatures are growing in importance as a legal standing with traditional handwritten signatures, most secure web transactions today are already dependent on digital signatures, which are included as part of the digital certificates a server ...

Digital signatures for modifiable collections [PDF]

open access: yesFirst International Conference on Availability, Reliability and Security (ARES'06), 2006
The common assumption about digital signatures is that they disallow any kind of modification on signed data. However, a more flexible approach is often needed and has been advocated lately, one in which some restricted modifications may still occur, without invalidating the data.

New number-theoretic cryptographic primitives

open access: yesJournal of Mathematical Cryptology, 2020
This paper introduces new prq-based one-way functions and companion signature schemes. The new signature schemes are interesting because they do not belong to the two common design blueprints, which are the inversion of a trapdoor permutation and the ...

On the validity of digital signatures

open access: yesACM SIGCOMM Computer Communication Review, 2000
An important feature of digital signatures is to serve as non-repudiation evidence. To be eligible as non-repudiation evidence, a digital signature on an electronic document should remain valid until its expiry date which is specified by some non-repudiation policy.

Digital signatures for flows and multicasts [PDF]

open access: yesIEEE/ACM Transactions on Networking, 1999
We present chaining techniques for signing/verifying multiple packets using a single signing/verification operation. We then present flow signing and verification procedures based upon a tree-chaining technique. Since a single signing/verification operation is amortized over many packets, these procedures improve signing and verification rates by one ...

Mathematical models of message authentication in the post-quantum cryptosystems based on error-correcting coding

open access: yesНаука. Инновации. Технологии, 2022
The paper discusses possibilities for use of message authentication signatures schemes based on error-correcting coding which may be candidates for use in post-quantum cryptography.

DEC‐LADE: Dual elliptic curve‐based lightweight authentication and data encryption scheme for resource constrained smart devices

open access: yesIET Wireless Sensor Systems, 2021
The fast growth in Internet‐of‐Things (IoT) applications has increased the number of end‐devices communicating over the Internet. As these resource‐constrained devices are connected over the Internet, they are exposed to various security and privacy ...

Revocable Quantum Digital Signatures [PDF]

open access: yes, 2023
We study digital signatures with revocation capabilities and show two results. First, we define and construct digital signatures with revocable signing keys from the LWE assumption.

Efficient proxy ring signature for VANET

open access: yesThe Journal of Engineering, 2019
The messages in vehicular ad hoc networks (VANET) are vulnerable to attack in the open wireless environment. Group communication in VANET is receiving more attention, which confronts many security issues.
