A PRACTICABLE TIMING ATTACK AGAINST HQC AND ITS COUNTERMEASURE
In this paper, we present a practicable chosen ciphertext timing attack retrieving the secret key of HQC. The attack exploits a correlation between the weight of the error to be decoded and the running time of the decoding algorithm of BCH codes. For the 128-bit security parameters of HQC, the attac...
