About this document
Fault Attack on Montgomery Ladder EC by Bedoui Wafa is a document available to read on EtoBox.
The document presents a new fault attack on elliptic curve scalar product algorithms that use the Montgomery ladder method when the y-coordinate is not used. The attack exploits the twist of the elliptic curve, which allows moving between a point on the original curve and its twist with about 50% probability by injecting a single fault. This can be used to retrieve the secret exponent even with countermeasures like exponent masking. The attack works on parameters from standards like NIST that do not properl
