- Fraunhofer Unveils Quantum Random Generator Aimed at Future Cryptographic Security Challenges
- Q-Dice uses vacuum fluctuations instead of software algorithms for randomness
- New system delivers quantum-generated random number output at over 4 Gbit/s
As concerns grow over the security implications of future quantum computers, researchers continue to search for stronger sources of cryptographic protection.
A critical requirement involves generating truly unpredictable random numbers that can withstand increasingly sophisticated attacks against modern digital systems.
Fraunhofer IPMS has now introduced a new quantum random number generator designed specifically for security-sensitive environments and high-performance infrastructure deployments.
Quantum randomness replaces reliance on conventional algorithms
The system, known as Q-Dice, generates random numbers using vacuum quantum fluctuations rather than conventional software algorithms that may contain weaknesses.
According to Fraunhofer IPMS, the technology offers randomness at speeds above 4 Gbit/s, while the hardware device is rated at 4.1 Gbit/s.
Random number generation is a critical component of encryption, authentication, secure communications, and access control systems across modern digital infrastructure.
Weak or predictable randomness can undermine otherwise strong security mechanisms, creating opportunities for attackers to exploit cryptographic vulnerabilities.
Because Q-Dice’s randomness originates from quantum vacuum fluctuations rather than a mathematical formula, there is no underlying pattern that hackers can study.
This means that there is no initial value that attackers can calculate, predict, or reverse engineer, regardless of the computing power available.
Fraunhofer IPMS says Q-Dice derives entropy from inherently unpredictable quantum effects, producing results suitable for applications including data encryption, authentication systems, secure communications, quantum key distribution and post-quantum cryptography.
The organization states that the randomness generated was evaluated using recognized frameworks, including BSI AIS 20/31 and the NIST SP 800-22 test suite.
The system also has EAL 3 and PTG 3 ratings, reflecting compliance with the security requirements set by the German Federal Office for Information Security.
Unlike many software-based approaches, the platform relies on quantum physical phenomena rather than mathematical procedures intended to simulate randomness.
Rack-mounted hardware and cloud access offer deployment flexibility
Fraunhofer IPMS offers the technology through dedicated hardware and cloud-based delivery models to adapt to different operational requirements.
The main hardware version arrives as a 19-inch rack-mounted device intended for deployment within data centers and other controlled computing environments.
The device combines quantum entropy generation, signal acquisition, randomness extraction and systems integration within a single platform with 10 Gbit/s Ethernet connectivity.
Fraunhofer IPMS said the development process remained entirely in-house and encompassed optical subsystem design, low-noise analog electronics, high-speed data acquisition and FPGA-based post-processing.
For organizations not willing to install dedicated equipment, the institute also offers an online entropy-as-a-service offering that delivers quantum-generated randomness through a secure interface.
“With Q-Dice, we make high-quality quantum randomness practically usable and accessible,” said Alexander Noack, director of the computing and data communications division at Fraunhofer IPMS.
“Whether as a robust 19-inch rack system integrated into your own infrastructure or through our online entropy-as-a-service platform, we are removing the barriers to adopting quantum-level security.”
Fraunhofer IPMS is now actively seeking partners to test the technology and help build real, practical applications around it.
Noack added that the goal involves working collaboratively to raise the overall level of security and trust as the capabilities of quantum computing continue to advance.
Whether Q-Dice becomes a standard component in next-generation security infrastructure or remains a niche tool depends on how quickly organizations recognize the urgency of post-quantum readiness.
