Lattice-based weak curve fault attack on ECDSA
Weiqiong Cao, Hongsong Shi, Hua Chen, and Wei Wei
Abstract
ECDSA algorithm is usually used in ICT system to achieve communication authenticity. But weakness in various implementations of the algorithm may make its security deviate from theoretical guarantee. This paper proposes a new lattice-based weak curve fault attack on ECDSA. An elliptic curve is weak if the problem of ECDLP in a \emph{subgroup} of the point group
