Abstract

The quasi-cyclic medium-density parity-check(QC-MDPC) code based McEliece public key cryptography(PKC) has good performance characteristics: both the key size and the algorithm complexity of the scheme are low. However, a key recovery attack can crack the scheme against its security. The attacker can collect reaction information of the decoding failure from the receiver by adding specific error patterns to the massage, then somehow reconstruct the secret key. To copy with this attack, this paper proposed some possible countermeasure. The countermeasure combined the automatic repeat-request(ARQ) with pseudo-random sequence to eliminate the validity of feedback information. The simulation results show that the countermeasure can effectively resist this attack. Finally, this paper compared the difference between the proposed countermeasure and other schemes, and analyzed its future improvement direction.
