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 ...

New DoS Defense Method Based on Strong Designated Verifier Signatures

open access: yesSensors, 2018
We present a novel technique for source authentication of a packet stream in a network, which intends to give guarantees that a specific network flow really comes from a claimed origin.

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.

Performance and Applicability of Post-Quantum Digital Signature Algorithms in Resource-Constrained Environments

open access: yesAlgorithms, 2023
The continuous development of quantum computing necessitates the development of quantum-resistant cryptographic algorithms. In response to this demand, the National Institute of Standards and Technology selected standardized algorithms including Crystals-

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.

Orthogonal Latin square theory based group and batch verification for digital signatures

open access: yesTongxin xuebao, 2022
In order to solve the problem of fast security verification of massive and time-intensive messages on a central node in situational awareness networks, orthogonal Latin square theory based scheme was considered.Considering efficiency promotion of ...

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 ...

Lattice‐based hash‐and‐sign signatures using approximate trapdoor, revisited

open access: yesIET Information Security, 2022
For the purpose of improving the efficiency of the cryptosystems built upon lattice trapdoors, Chen, Genise and Mukherjee at ASIACRYPT 2019 modified the gadget trapdoor (G‐trapdoor) to an approximate trapdoor, which enables one to sample short preimages ...
