- Fraunhofer Introduces Quantum Random Generator Targeting Future Cryptographic Security Challenges
- Q-Dice uses vacuum fluctuations instead of software algorithms for randomness
- New system provides quantum-generated random number output at over 4 Gbps
As concerns grow about the security implications of future quantum computers, researchers continue to look for stronger sources of cryptographic protection.
A key requirement is to generate truly unpredictable random numbers that can withstand increasingly sophisticated attacks on modern digital systems.
Fraunhofer IPMS has now introduced a new quantum random number generator designed specifically for security-sensitive environments and high-throughput infrastructure deployments.
Quantum chance replaces the use of conventional algorithms
The system, known as Q-Dice, generates random numbers using quantum vacuum fluctuations rather than conventional software algorithms that may contain weaknesses.
According to Fraunhofer IPMS, the technology delivers randomness at speeds above 4 Gbps, with the hardware appliance rated at 4.1 Gbps.
Random number generation is a fundamental part of encryption, authentication, secure communications and access control systems across modern digital infrastructure.
Weak or predictable randomness can undermine otherwise robust security mechanisms, creating opportunities for attackers to exploit cryptographic vulnerabilities.
Since Q-Dice’s randomness comes from fluctuations in the quantum vacuum rather than a mathematical formula, there is no underlying pattern for hackers to study.
This means that there is no starting point for attackers to calculate, predict, or reverse engineer, regardless of the available computing power.
According to Fraunhofer IPMS, Q-Dice derives entropy from inherently unpredictable quantum effects, producing results suitable for applications such as data encryption, authentication systems, secure communications, quantum key distribution and post-quantum cryptography.
The organization claims that generated randomness was assessed using recognized frameworks, including BSI AIS 20/31 and the NIST SP 800-22 test suite.
The system also carries the EAL 3 and PTG 3 classifications, reflecting compliance with security requirements established by the German Federal Office for Information Security.
Unlike many software approaches, the platform relies on physical quantum phenomena rather than mathematical procedures intended to simulate chance.
Rack-mounted hardware and cloud access provide deployment flexibility
Fraunhofer IPMS offers the technology via dedicated hardware and cloud-based delivery models to meet different operational requirements.
The primary hardware version comes in the form of a 19-inch rack-mounted appliance intended for deployment in data centers and other controlled computing environments.
The appliance combines quantum entropy generation, signal acquisition, random extraction and systems integration into a single platform with 10 Gbps Ethernet connectivity.
Fraunhofer IPMS said the development process remains entirely in-house, covering optical subsystem design, low-noise analog electronics, high-speed data acquisition and FPGA-based post-processing.
For organizations that do not wish to install dedicated equipment, the institute also offers an online Entropy-as-a-Service offering providing quantum-generated randomness via a secure interface.
“With Q-Dice, we are making high-quality quantum randomness practically usable and accessible,” said Alexander Noack, Director of the Data Communication and Computing Division at Fraunhofer IPMS.
“Whether as a rugged 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 pilot the technology and help create practical, real-world applications around it.
Noack added that the goal involves working collaboratively to raise the overall bar for security and trust as quantum computing capabilities continue to advance.
Whether Q-Dice becomes a standard component of next-generation security infrastructure or remains a niche tool depends on how quickly organizations recognize the urgency of post-quantum preparedness.
