Quantum developments pose a critical threat to modern cybersecurity technologies and are of grave concern to the confidentiality, integrity, and privacy of personal information, business interests, and national security. The potentially drastic repercussions on cybersecurity by the commercial availability of quantum computers in the next decade or so is driving the development of quantum-safe cryptography. Also known as post-quantum cryptography, such research looks to the development of new cryptographic algorithms that could withstand breaking by quantum computers. This report looks at two different but related concepts in the field of cryptography. The first examines efforts to develop quantum-safe cryptographic technologies (post-quantum cryptography or PQC). The second analyzes current commercialized solutions in cryptography that make use of quantum mechanics: QKD. The final section of the report provides an overview of vendors in the space.
