At MWC Barcelona 2025, Quantum Dice and AT&T will collaboratively demonstrate an implementation of Entropy-as-a-Service powered by Quantum Dice and its use in a DQKD VPN use case created by AT&T.
Quantum Dice’s new QEaaS solution leverages its patented DISCTM Quantum Random Number Generator (QRNG) to distribute high-quality entropy across remote servers. This solution aims to solve one of the most fundamental challenges in modern cybersecurity: generating and securely distributing true random numbers for use as encryption keys.
Connecting with AT&T shows how carrier-grade infrastructure could be leveraged as a crypto-agile Entropy-as-a-Service platform. This sets the scene for making Entropy-as-a-Service a standard platform in mobility, whilst offering end-users a selection (or combination) of multiple entropy sources.
Entropy-as-a-Service ensures that even the most resource-limited devices and cloud instances receive the secure, certified randomness they need to implement all their cryptographic functions.
The Challenge
In today’s digital landscape, cybersecurity is critical to protect data and communications. Random numbers underpin that. Hardware-based random number generators (RNGs) and software-based pseudo-random number generators (PRNGs) are commonly used for generating encryption keys. However, both have inherent weaknesses that limit their effectiveness, especially in the face of evolving cybersecurity threats.
- Verification Difficulty: It is exceedingly difficult to verify or quantify the randomness produced by these existing methods, particularly over long operational periods. This can result in weaknesses that adversaries might exploit.
- Entropy Shortages: As encryption methods grow more complex, the demand for high-quality entropy — or true randomness — has increased significantly. The shortcomings of traditional methods are increasingly apparent, especially in the context of quantum-safe encryption and post-quantum cryptography.
Why High-Quality Randomness is Critical
As encryption techniques evolve, so do the demands on the systems that protect our data. Key trends driving the need for high-quality randomness include:
● Larger Key Sizes: Next-generation Post-Quantum Cryptography (PQC) algorithms require larger key sizes. These larger keys demand significantly more entropy than classical encryption methods.
● Increased Entropy Requirement: Symmetric encryption algorithms like AES (Advanced Encryption Standard) need not only larger keys but also sufficient entropy. Without it, these systems become vulnerable to quantum computer-based attacks, such as Grover’s Search.
● Quantum-Safe Encryption Keys: Current methods for expanding entropy to generate keys are vulnerable to quantum-based attacks, which makes them unsuitable in the face of emerging quantum technologies.
The Solution: DISC™ protected Quantum Random Number Generation (QRNG)
Quantum Dice has developed a novel Quantum Entropy-as-a-Service (QEaaS) solution that is backed by their DISC™ protocol. This offers distinct advantages over traditional RNG and PRNG methods:
- Live Entropy Verification: Quantum Dice’s DISCTM QRNG allows for continuous, real-time verification of entropy, ensuring that the randomness is of the highest quality at all times.
- Source Independence & Environmental Resilience: The quantum RNG is resistant to environmental factors, offering robust and reliable randomness even in challenging operating conditions.
- High-Quality True Randomness: Quantum Dice’s technology leverages quantum mechanics to provide genuine randomness — a key advantage over classical methods.
QEaaS is easy to consume and simple for any device to integrate with. Users can choose to host their own QRNG hardware or simply sign up to QEaaS remotely.
QEaaS in Action: An Example
At MWC Barcelona 2025, Quantum Dice and AT&T will showcase an implementation of QEaaS in action, powering a DQKD VPN. This demonstration will highlight how QEaaS provides the secure, high-entropy random numbers needed to power quantum-safe encryption technologies, helping to future-proof critical infrastructure.
Conclusion: QEaaS – A Solution for Now, and the Future
The need for true, verifiable randomness in encryption has never been more urgent. Whether in a post-quantum world or today, high-quality randomness is fundamental to the encryption protocols securing our data and communications. QEaaS is the next step in the evolution of Quantum Random Number Generation, providing a future-proof solution to the entropy crisis — one that is needed now, not just in a post-quantum world.
