Quantum computing is increasingly seen as a threat to communications security: rapid progress towards realizing practical quantum computers has drawn attention to the long understood potential of such machines to break fundamentals of contemporary cryptographic infrastructure. While this potential is so far firmly theoretical, the cryptography community is preparing for this possibility by developing Post-Quantum Cryptography (PQC), that is, cryptography resisting the increased capabilities of quantum computers. In this white paper, we explore the background, impact, and urgency of this threat, and summarize the cryptographic schemes being evaluated. We also provide recommendations on what steps should be taken today to be prepared for the changes to come, and discuss how Arm is approaching PQC.
