Elliptic curve cryptosystems proved to be well suited for securing systems with constrained resources like embedded and portable devices. In a fault-based attack, errors are induced during the computation of a cryptographic primitive, and the results are collected to derive information about the secret key safely stored in the device. We introduce a novel attack methodology to recover the secret key employed in implementations of the Elliptic Curve Digital Signature Algorithm. Our attack… CONTINUE READING
