In cybersecurity, quantum computing presents both exciting new possibilities and threats to data confidentiality, integrity and security. While it promises unparalleled computational power, it also poses a significant risk to current encryption methods, which rely on mathematical problems that could be solved on a quantum computer running Shor’s algorithm. As quantum computing advances, the urgency for Post-Quantum Cryptography (PQC) becomes increasingly evident.PQC involves the development of stronger algorithms with significantly longer key lengths, which are designed to secure against both quantum and classical attacks. The adoption of these new algorithms presents its own set of complexities. From increased compute consumption to latency issues, the implications across networks and services are significant.In this dynamic environment, testing is pivotal in ensuring a seamless transition to PQC. By evaluating performance metrics and user experiences, organizations can proactively address potential challenges and ensure smooth adoption.Industry stakeholders emphasize the importance of testing. SoftBank warns of potential latency issues and communication quality degradation, underscoring the need for robust testing protocols. Similarly, GSMA highlights the necessity for mobile operators to assess server capabilities to be able to accommodate larger cipher texts and signatures.Government mandates further underscore the urgency. The U.S. Federal government’s memorandum to migrate existing public key cryptographic systems to PQC marks a shift in the cybersecurity landscape. With governments leading the charge, businesses across sectors must respond accordingly.Market projections reinforce the magnitude of this transition. IQT predicts exponential growth in the PQC market, with significant investments earmarked for upgrades and testing solutions. As stakeholders brace for this transformative shift, attention turns to innovative testing methodologies.SOURCE: Inside Quantum Technology, “Post-Quantum Cryptography 2023: Market Opportunities After NIST” (link) The First PQC Testing Solutions on the MarketLeveraging its extensive experience in testing and assuring large-scale and complex networks, VIAVI has introduced the industry’s first cloud-enabled test platform to support PQC algorithms mandated by the U.S. National Institute of Standards and Technology (NIST).
