Accelerated Verification of ECDSA Signatures [PDF]
, 2006 Verification of ECDSA signatures is considerably slower than generation of ECDSA signatures. This paper describes a method that can be used to accelerate verification of ECDSA signatures by more than 40% with virtually no added implementation complexity. The method can also be used to accelerate verification for other ElGamal-like signature algorithms,

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

Some lattice attacks on DSA and ECDSA [PDF]
Applicable Algebra in Engineering, Communication and Computing, 2011 This paper develops attacks on DSA and ECDSA using the algorithm for LLL reduction and two algorithms for the computation of the integral points of two classes of conics, provided that the secret and the ephemeral key of a signed message or their modular inverses are sufficiently small and in case the ephemeral keys or their modular inverses of two ...
