Making network communications unhackable

CST Global has developed Quantum Key Distribution (QKD) emitter and detector technologies as part of a UK-funded, government project. These technologies can enable totally secure, network communications. QKD suits mission-critical, client server applications, where unbreakable security codes prevent hacking and malicious attack. QKD can be applied to existing IT infrastructures and offers a high-security, data transmission option within the rapidly expanding, optical communications market*.

QKD has been developed as part of CST Global’s core competence in Quantum technologies. QKD is a result of CST Global’s involvement in the QR-SPLED,government-funded project and the ‘Single Photon Infrared Detectors for Quantum Systems’ project with Amythest research and Lancaster University.

QKD requires single-photon, Quantum Light Source (QLS) to transmit data and a Single-Photon Detector (SPD) to receive it. CST Global has both QLS and SPD technologies developed to microscale, through government-funded projects. The SPD receiver also operates at room temperature, instead of at the impractical, cryogenic temperatures of previous solutions.

Andrew McKee, CTO at CST Global, explains, “High-security authentication of client server sessions in today’s IT infrastructures are encrypted via a secure, HTTPS key server. CST Global’s QKD solution will also do this, however, it can encrypt every single packet of data within a session, in real timemaking it significantly more secure. However, QKD’s speed allows direct client servercommunications and it will detect tamper attemptsaborting ‘suspect’ sessionsThis makes QKD-based network security totally un-hackable.”

CST Global’s QKD solution operates at room temperature and is potentially small enough, cheap enough and practical enough for deployment in pc, server or smartphone applicationsThe company is actively seeking a commercial partner interested in developing a dedicated, nanoscale chip for widespread use.
