ePrint Report: Fault Attacks on UOV and Rainbow

Juliane Krämer, Mirjam Loiero

Multivariate cryptography is one of the main candidates for
creating post-quantum public key cryptosystems. Especially in the area of digital signatures, there exist many practical and secure multivariate schemes. The signature schemes UOV and Rainbow are two of the most promising and best studied multivariate schemes which have proven secure
for more than a decade. However, so far the security of multivariate signature schemes towards physical attacks has …
