PacketLight Networks has partnered with Quantum XChange to integrate post-quantum cryptography into its optical transport hardware, bolstering its existing FIPS-certified Layer-1 encryption and Quantum Key Distribution framework. This collaboration incorporates National Institute of Standards and Technology (NIST) post-quantum cryptographic standards, enhancing the security of PacketLight's optical transport solutions. The integration of advanced post-quantum cryptography is a response to the looming threat of quantum computing to classical encryption methods. As quantum computing capabilities advance, the need for crypto-agile optical transport solutions becomes increasingly urgent1. The partnership between PacketLight and Quantum XChange aims to future-proof optical transport networks against potential quantum attacks. This development matters to practitioners because it underscores the growing importance of planning for cryptographic migration in the face of accelerating quantum developments, which narrows the timeline for implementing post-quantum cryptography.
