The importance goes beyond the need for secure commercial communication – government and military are also strong users of satellite communications. Quantum-resilient cryptographic communications satellite link via Starlink “QuSecure’s breakthrough in secure satellite communications capabilities creates the world’s first extraterrestrial post-quantum resilient communications mesh and is a very important step in our collective journey toward quantum safety,” said Aaron Moore, QuSecure’s EVP, Head of Engineering. This is important since air-borne data traffic can be sniffed and is, if anything, more susceptible to the ‘harvest now, decrypt later’ threat. The latest development now announced is that this quantum resilient link can be extended to satellite communications – meaning the link between an end user and, for example, a website will be quantum resilient even via a satellite connection. It is described it as the first quantum-safe orchestration solution protecting encrypted private data on any website or mobile application with quantum-resilient connections and sessions, all with no end-user installation required. QuEverywhere was launched in January 2023. The keys are delivered to QuEverywhere via a QSL tunnel, which adds quantum resiliency to TLS. “It’s all just a policy configuration and it’s very simple.” Currently, QuSecure defaults to the Quintessence quantum random number generator, and the Kyber algorithm. “We support the entire suite of finalists,” co-founder and CPO, Rebecca Krauthamer, told SecurityWeek. Agility implies an effortless ability to switch from one algorithm to another, as necessary or simply desired. They will need to be replaced by other or new or simply stronger algorithms. Nobody expects the recommended algorithms to last forever – the likelihood is that some, if not all, will eventually fail. It supports all NIST recommended post-quantum algorithms, and can interface with any quantum random number generator ( QRNG). The philosophy is to provide absolute agility. Quark is described as the brain of the QuSecure solution and is the key distribution platform. The journey starts at Quark (QuSecure Orchestrator). It protects data delivered by satellite from classical- and quantum-computer decryption. Quantum cybersecurity firm QuSecure has announced the first known end-to-end quantum resilient encrypted communications link via satellite.
