Committing to quantum resistance: a slow defence for Bitcoin against a fast quantum computing attack [PDF]

Royal Society Open Science, 2018
Quantum computers are expected to have a dramatic impact on numerous fields due to their anticipated ability to solve classes of mathematical problems much more efficiently than their classical counterparts. This particularly applies to domains involving

Blind ECDSA from the ECDSA Assumption

IACR Communications in Cryptology
Blind signatures have become a cornerstone for privacy-sensitive applications such as digital cash, anonymous credentials, and electronic voting. The elliptic curve variant of the Digital Signature Algorithm (ECDSA) is widely adopted due to its efficiency in resource-constrained environments, such as mobile devices and blockchain systems.

From A to Z: Projective coordinates leakage in the wild

Transactions on Cryptographic Hardware and Embedded Systems, 2020
At EUROCRYPT 2004, Naccache et al. showed that the projective coordinates representation of the resulting point of an elliptic curve scalar multiplication potentially allows to recover some bits of the scalar.

The Security of DSA and ECDSA [PDF]

, 2002
DSA and ECDSA are well established standards for digital signature based on the discrete logarithmp roblem. In this paper we survey known properties, certification issues regarding the public parameters, and security proofs.ECDSA also includes a standard certification scheme for elliptic curve which is assumed to guarantee that the elliptic curve was ...

When one vulnerable primitive turns viral: Novel single-trace attacks on ECDSA and RSA

Transactions on Cryptographic Hardware and Embedded Systems, 2020
Microarchitecture based side-channel attacks are common threats nowadays. Intel SGX technology provides a strong isolation from an adversarial OS, however, does not guarantee protection against side-channel attacks. In this paper, we analyze the security
