  • First reference code package targeting spec v4.0 containing some bugs making this implementation inconsistent with some aspects of spec v4.0. We note that between 2020.05.01 and 2020.05.03, versions of the specification and reference code have been uploaded to our website. Some of those documents were inconsistent with one another. The correct version for both is BIKE_Spec.2020.05.03.1.pdf and Reference_Implementation.2020.05.03.1.pdf.

  • The variable MAX_J_SIZE has been changed to N_BITS in order to ensure that matrix J (used in the decoder) always has enough allocated memory to store the variable number of indices;
  • Variables MAX_IT_LOOP1 and MAX_IT_LOOP2 have been added to ensure that the loops present in Algorithm 3 (One-Round Bit-Flipping) always terminate.
