Tech Update: Quantum-Safe over Long-Haul Subsea + Terrestrial

Sparkle has just completed the first quantum-encrypted Internet Protocol secure (IPsec) tunnel between Italy and Germany using Arqit’s Symmetric Key Agreement Platform. Curious about the future of quantum-safe VPNs and how they can revolutionize your business operations? Daniele Mancuso, Chief Marketing and Product Management from Sparkle, explains:

- The successful completion of the first proof of concept of a Quantum-safe VPN IPC VPN between Sicily and Frankfurt, a 2,000 km network that spans on top of terrestrial and subsea networks. This is the first trial on a production network that spans between two countries.

- The anticipation of the advent of quantum computers, which could disrupt current cryptographic algorithms. Sparkle is already preparing for this possible disruption, with a commercial launch planned by the end of the year. This will provide an upgrade to customers, offering a software-based VPN that allows the exchange of symmetrical keys that are quantum resistant.

- The ongoing infrastructure developments, including the completion of a flagship data center in Panama, the upgrade of a second module of a data center in Metamorphosis, and the announcement of a new infrastructure in the Mediterranean called Green Med.

Sparkle tests IPsec VPN with quantum encryption over fiber network

Sparkle and Arqit Quantum Inc., company specialized in quantum-safe encryption, completed a Proof of Concept (PoC) on the first Internet Protocol secure (IPsec) tunnel between Italy and Germany using Arqit’s Symmetric Key Agreement Platform. The test was supported by Telsy, a TIM Group company specialized in cybersecurity.

The PoC showcases the integration of Quantum Arqit's technology using Symmetric Key Agreement (SKA) into Sparkle's state-of-the-art network infrastructure, ensuring enhanced encryption methods for data transmission across geographical borders.

Sparkle describes the test as the first step toward a software quantum-safe Virtual Private Network (VPN). Being software based, the SKA Platform is quickly and easily scaled across any existing telecom network ensuring that sensitive data remains protected against potential decryption by future quantum algorithms, thereby mitigating the risks associated with evolving cybersecurity threats.

Daniele Mancuso, Sparkle's Chief Marketing & Product Management Officer said: “Our state-of-the-art global network provides critical services to carriers, institutions and enterprises who choose and trust Sparkle’s leading secure connectivity services to keep their data safe. The successful completion of the quantum-safe VPN PoC, preliminary to a large-scale commercial launch, anticipates the potential threat of quantum decryption and confirms our market leading commitment to continuously elevating the security and resilience of Sparkle’s infrastructure.” 

David Williams, Arqit Founder, Chairman and CEO said: “Sparkle’s establishment of the first quantum-safe VPN between Catania and Frankfurt signifies a key milestone in telecoms cybersecurity. By leveraging Arqit's SKA Platform, Sparkle is pioneering a new era of secure communication, ensuring the resilience of critical networks against the looming threat of quantum adversaries.”

Tech Update: Can Global Carriers Keep Ahead of AI Data Center Demands?

Almost every day we hear of new AI data center projects all around the world. Is the international infrastructure, including subsea cables, keeping up with the exponential increase in data traffic? Speaking at ITW in Washington, D.C., Michael Trabbia, CEO from Orange Wholesale explains:

- The global internet experiences a 20 to 30% traffic growth every year, necessitating a dramatic increase in infrastructure. This includes submarine cables, long haul fiber, and the backbone of the internet that needs constant rebuilding to accommodate the data traffic surge.

- Orange manages extensive infrastructure, including 450,000 km of submarine cables, 45,000 km of backbone fiber, and 27,000 towers for mobile subscribers. This infrastructure is key to their strategy and they continue to invest in it, not only to serve their customers but also to collaborate with other telcos worldwide to ensure the internet remains global.

- Despite the increasing demand for traffic, Trabbia remains optimistic about the ability to invest fast enough in the infrastructure to manage it. The traffic growth is well-known, and they know the routes to invest in and how to work together with other telcos to mutualize the investment. This collaboration will continue to improve the quality of the internet and prepare it for the demands of generative AI and the internet of tomorrow.

DC BLOX completes Myrtle Beach to Atlanta fiber route

DC BLOX activated a new dark fiber route connecting its Myrtle Beach Cable Landing Station (CLS) to Atlanta. The new high-capacity East-West route serves as the new backbone to the Southeast region enabling hyperscalers, global and regional communications providers, local ISPs and enterprises to connect regionally and internationally.

In October 2023, DC BLOX completed its new Cable Landing Station (CLS) in Myrtle Beach, South Carolina. The new fiber route provides direct terrestrial connectivity from the CLS to the rapidly growing data center and communications center of Atlanta. The route runs from Myrtle Beach, SC, near Charleston, SC, through Augusta, GA to the major downtown connectivity centers in Atlanta including 56 Marietta Street, and on to the growing data center base in Lithia Springs, GA.

“With our regional colocation data centers, the Myrtle Beach CLS, our regional network, and this new dark fiber route, DC BLOX is building the infrastructure needed to support the Southeast’s rapid growth,” said Kurt Stoever, Chief Operating Officer of DC BLOX. “Digital infrastructure is the foundation that will drive the economies of the 21st century, and DC BLOX is proud to be enabling our communities to thrive.”

DC BLOX is also building a dark fiber ring around Atlanta which will connect into two hyperscale-ready data center facilities in development east and west of the city. The metro-Atlanta fiber ring will also connect to the East-West route further expanding global connectivity options from the area.
