Differential Fault Analysis of Rectangle-80
Abstract
We present various differential fault attack schemes for the RECTANGLE-80 and demonstrate how initially we started from a 80-bit fault to a single word fault scheme. This was mainly due to a differential vulnerability in the S-box of RECTANGLE as a result of which the exhaustive search space for the key reduces from $2^{80}$ to $2^{32}$. We have also presented a key schedule attack that is a variant of the single fault scheme, exploiting the same vulnerability and reduces the search space to $2^{40}$. The paper concludes with the simulation results for the single word fault scheme followed by countermeasures.
