Safe-Errors on SPA Protected implementations with the Atomicity Technique
Elliptic Curve Cryptography Side-Channel Atomicity Fault Attacks
2015/12/24
ECDSA is one of the most important public-key signature scheme, however it is vulnerable to lattice attack once a few bits of the nonces are leaked. To protect Elliptic Curve Cryptography (ECC) agains...
SPA-based attack against the modular reduction within a partially secured RSA-CRT implementation
RSA CRT smartcard implementation
2009/3/27
This note describes an SPA-based side channel attack against a CRT implementation of an RSA
function. In contrast with Novak’s attack [8], it concentrates on the initial modular reduction. With the h...
SPA resistant left-to-right integer recodings
SPA resistant left-to-right integer recodings
2009/2/6
We present two left-to-right integer recodings which can be used to
perform scalar multiplication with a fixed sequence of operations. These recodings
make it possible to have a simple power analys...
