Verizon tests Quantum Key Distribution

Verizon set-up a trial Quantum Key Distribution (QKD) network in the Washington D.C. area.

Live video was captured outside of three Verizon locations in the D.C. area, including the Washington DC Executive Briefing Center, the 5G Lab in D.C and Verizon’s Ashburn, VA office. Using a QKD network, quantum keys were created and exchanged over a fiber network between Verizon locations. Video streams were encrypted and delivered more securely allowing the recipient to see the video in real-time while ensuring hackers are instantly detected.

A QKD network derives cryptographic keys using the quantum properties of photons to prevent against eavesdropping. Verizon also demonstrated that data can be further secured with keys generated using a Quantum Random Number Generator (QRNG) that creates truly random numbers that can’t be predicted. With QKD, encryption keys are continuously generated and are immune to attacks because any disruption to the channel breaks the quantum state of photons signaling
eavesdroppers are present.

"The use of quantum mechanics is a great step forward in data security,” said Christina Richmond, analyst at IDC. “Verizon's own tests, as well other industry testing, have shown that deriving "secret keys" between two entities via light photons effectively blocks perfect cloning by an eavesdropper if a key intercept is attempted. Current technological breakthroughs have proven that both the quantum channel and encrypted data channel can be sent over a single optical fiber. Verizon has demonstrated this streamlined approach brings greater efficiency for practical large-scale implementation allowing keys to be securely shared over wide-ranging networks.”

Dell’Oro: Open RAN market to eclipse $5 billion

The worldwide sales of Virtualized Open RAN technologies are forecasted to grow at double-digit rates over the next five years with cumulative Open RAN investments – including hardware, software, and firmware excluding services – projected to surpass $5 B over the forecast period, according to a new report from Dell'Oro Group.

“At a first glance it might appear overly optimistic with a baseline scenario suggesting a new technology, which remains relatively untested and some officials believe would need a decade to get off the ground, would be able to become a billion-dollar market comprising a sizable portion of the overall RAN segment in just half a decade,” said Stefan Pongratz, Vice President and analyst with the Dell’Oro Group. “At the same time, the momentum is improving, and we have adjusted the outlook upward to reflect a confluence of factors including promising results from initial commercial deployments, growing support from the incumbent RAN suppliers, and increased geopolitical uncertainty acting as a catalyst for operators to rethink their supplier strategies,” continued Pongratz.

Additional highlights:

  • Cumulative Virtualized RAN revenues—here defined as the proportion of RAN baseband/compute capex that will utilize general-purpose processors for CU and/or DU—are projected to approach $3 B to 5 B over the next five years.
  • Cumulative Open RAN radio shipments – including macro and small cells – are projected to surpass 1 M over the forecast period.
