Loop Aborts Strike Back: Defeating Fault Countermeasures in Lattice Signatures with ILP

At SAC 2016, Espitau et al. presented a loop-abort fault attack against lattice-based signature schemes following the Fiat–Shamir with aborts paradigm. Their attack recovered the signing key by injecting faults in the sampling of the commitment vector (also called masking vector) y, leaving its coe...
