Weak-Key Analysis for BIKE Post-Quantum Key Encapsulation Mechanism. (arXiv:2204.13885v2 [cs.CR] UPDATED)

The evolution of quantum computers poses a serious threat to contemporary
public-key encryption (PKE) schemes. To address this impending issue, the
National Institute of Standards and Technology (NIST) is currently undertaking
the Post-Quantum Cryptography (PQC) standardization project intending to
evaluate and subsequently standardize the suitable PQC scheme(s). One such
attractive approach, called Bit Flipping Key Encapsulation (BIKE), has made to
the final round of the competition. Despite having some attractive features,
the IND-CCA security of the BIKE depends on the …
