Cryptographic primitives are fundamental building blocks for designing security protocols to
achieve confidentiality, authentication, integrity and non-repudiation. It is not too much to say …

Abstract We apply the Flush+ Reload side-channel attack based on cache hits/misses to
extract a small amount of data from OpenSSL ECDSA signature requests. We then apply a …

We introduce Four Q, a high-security, high-performance elliptic curve that targets the 128-bit
security level. At the highest arithmetic level, cryptographic scalar multiplications on Four Q …

We select a set of elliptic curves for cryptography and analyze our selection from a
performance and security perspective. This analysis complements recent curve proposals …

Verification of an ECDSA signature requires a double scalar multiplication on an elliptic
curve. In this work, we study the computation of this operation on a twisted Edwards curve …

This work deals with the energy-efficient, high-speed and high-security implementation of
elliptic curve scalar multiplication, elliptic curve Diffie-Hellman (ECDH) key exchange and …

Elliptic curve cryptosystems are considered an efficient alternative to conventional systems
such as DSA and RSA. Recently, Montgomery and Edwards elliptic curves have been used …

This paper presents new speed records for arithmetic on a large family of elliptic curves with
cofactor 3: specifically, 8.77 M 8.77 M per bit for 256-bit variable-base single-scalar …

We present high-speed implementations of the post-quantum supersingular isogeny Diffie-
Hellman key exchange (SIDH) and the supersingular isogeny key encapsulation (SIKE) …

This paper sets new speed records for high-security constant-time variable-base-point Diffie–
Hellman software: 305395 Cortex-A8-slow cycles; 273349 Cortex-A8-fast cycles; 88916 …
