Quantum-Safe Connectivity Now Available on AWS Marketplace: Secure Data with Sparkle’s QSI

Sparkle, an international telecommunications provider, has made its Quantum Safe over Internet (QSI) service available to customers on the Amazon Web Services (AWS) Marketplace. QSI provides secure VPN connectivity between customer locations and cloud resources, designed to mitigate risks posed by future quantum computing attacks. Validated through a Proof-of-Concept across AWS regions in Frankfurt and Ireland, the cloud-native service operates without infrastructure changes, utilising Sparkle’s network and encryption technologies to ensure data transmission with automated management, and is accessible via a dedicated portal or API. Launched commercially in December 2024, QSI represents the first offering within Sparkle’s planned suite of multi-quantum solutions.

Sparkle has extended the availability of its Quantum Safe over Internet (QSI) service to Amazon Web Services (AWS) customers via the AWS Marketplace, previously offered through direct channels, enhancing data connectivity and redefining how organisations protect data transmission while driving innovation. The service delivers a cloud-native solution for secure Virtual Private Network (VPN) connectivity between customer locations or data centres and cloud providers, mitigating risks posed by the development of quantum computing. It operates without necessitating alterations to existing infrastructure, leveraging Sparkle’s network and advanced encryption technologies to ensure rapid and secure data transmission, managed through a dedicated portal or Application Programming Interface (API). The QSI service represents the initial offering within Sparkle’s Multi-Quantum solutions suite, with further use cases planned for future release, expanding the scope of protection beyond VPN connectivity.

Validation of the service’s efficacy was demonstrated through a Proof-of-Concept (PoC) conducted across AWS regions in Frankfurt and Ireland, confirming the establishment of secure, quantum-safe VPN tunnels. The PoC maintained continuous key rotation and encryption integrity without compromising performance, demonstrating a viable pathway to enhanced security. Results indicated that the implemented solution maintained data transmission rates comparable to conventional VPN setups, demonstrating a viable pathway to enhanced security without substantial performance penalties. Continuous key rotation formed a central component of the validation process, demonstrating the automated and secure exchange of encryption keys, mitigating the risk of compromise through prolonged key usage.

Sparkle’s Network as a Service (NaaS) approach facilitates integration with existing IT infrastructure, allowing for dynamic scaling of bandwidth and security parameters responding to fluctuating network demands and evolving threat profiles. This flexibility proves particularly valuable for organisations adopting hybrid cloud architectures and requiring consistent security policies across diverse environments, ensuring interoperability with existing security infrastructure. The initial deployment of QSI represents a foundational element within Sparkle’s broader Multi-Quantum strategy.

Sparkle intends to broaden its Multi-Quantum solutions suite beyond the initial Quantum Safe over Internet (QSI) offering, focusing development on addressing emerging security requirements and integrating complementary technologies. Planned expansions include investigation into quantum key distribution (QKD) systems to provide an alternative method for secure key exchange, independent of computational assumptions, and assessing the feasibility of hybrid approaches combining post-quantum cryptography with QKD. Further research encompasses the implementation of post-quantum digital signatures, crucial for verifying data integrity and authenticity in a post-quantum environment, evaluating various schemes considering signature size, verification speed, and computational overhead.

The company also explores the application of quantum-enhanced encryption techniques beyond VPN connectivity, investigating the potential for securing data at rest, protecting sensitive databases and storage systems from quantum-based attacks. Sparkle’s approach prioritises a layered security model, combining multiple cryptographic techniques to provide defence in depth, mitigating the risk of a single point of failure, and actively collaborating with technology partners and research institutions to accelerate development. Future iterations of the suite will focus on automation and orchestration capabilities, developing tools for managing and monitoring quantum-safe security policies, simplifying deployment and reducing operational complexity for customers.
