Batch Verification of ECDSA Signatures
2012In this paper, we study several algorithms for batch verification of ECDSA signatures. The first of these algorithms is based upon the naive idea of taking square roots in the underlying field. We also propose two new and efficient algorithms which replace square-root computations by symbolic manipulations.

A Subliminal-Free Variant of ECDSA
2007A mode of operation of the Elliptic Curve Digital Signature Algorithm (ECDSA) is presented which provably excludes subliminal communication through ECDSA signatures. For this, the notion of a signature scheme that is subliminal-free with proof is introduced which can be seen as generalizing subliminal-free signatures and being intermediate to the ...

Fast Threshold ECDSA with Honest Majority
2020ECDSA is a widely adopted digital signature standard. A number of threshold protocols for ECDSA have been developed that let a set of parties jointly generate the secret signing key and compute signatures, without ever revealing the signing key. Threshold protocols for ECDSA have seen recent interest, in particular due to the need for additional ...

A novel fault attack against ECDSA
2011 IEEE International Symposium on Hardware-Oriented Security and Trust, 2011A novel fault attack against ECDSA is proposed in this work. It allows to retrieve the secret signing key, by means of injecting faults during the computation of the signature primitive. The proposed method relies on faults injected during a multiplication employed to perform the signature recombination at the end of the ECDSA signing algorithm ...

ECDSA-compatible Delegable Undeniable Signature
Proceedings of the 16th International Joint Conference on e-Business and Telecommunications, 2019We present the first ECDSA-compatible delegable undeniable signature. Undeniable signature was first introduced by Chaum and Antwerpen. Such signatures cannot be verified without running a zero-knowledge protocol with the signer. Delegable undeniable signature extends this by allowing the signer to delegate the verification ability to a third party. An

Implementation of ECDSA in WSN
2013 International Conference on Control Communication and Computing (ICCC), 2013Wireless sensor networks (WSN's) have been finding their application in diversified fields. Certain WSN applications used in military and commercial fields require the data communication within the network to be secure and confidentiality of the data needs to be maintained. Any WSN security model requires key services, authentication and integrity.

Analysis of ECDSA Authentication Processing in VANETs
2009 3rd International Conference on New Technologies, Mobility and Security, 2009Transport safety applications aim at avoiding vehicular accidents by using secure broadcast vehicle-to-vehicle (V2V) communications. However, any security mechanism used for authenticating broadcast V2V messages comes with overhead in terms of computation and communications.
