- Fraunhofer introduces quantum random generator aimed at future cryptographic security challenges
- Q-Dice uses vacuum oscillations instead of software algorithms for randomness
- New system delivers over 4 Gbit/s quantum generated random number output
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 the generation of 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-capacity infrastructure installations.
Quantum randomness replaces reliance on conventional algorithms
The system, known as Q-Dice, generates random numbers using quantum vacuum oscillations instead of conventional software algorithms that may contain weaknesses.
According to Fraunhofer IPMS, the technology delivers randomness at speeds in excess of 4 Gbit/s, with the hardware unit rated at 4.1 Gbit/s.
Random number generation forms a fundamental component of encryption, authentication, secure communication and access control systems throughout modern digital infrastructure.
Weak or predictable randomness can undermine otherwise robust security mechanisms and create opportunities for attackers to exploit cryptographic vulnerabilities.
Because Q-Dice randomness derives from quantum vacuum fluctuations rather than a mathematical formula, there is no underlying pattern for hackers to study.
This means that no initial value exists for attackers to calculate, predict or reverse engineer, regardless of available computing power.
Fraunhofer IPMS says Q-Dice derives entropy from inherently unpredictable quantum effects, producing outputs suitable for applications including data encryption, authentication systems, secure communications, quantum key distribution and post-quantum encryption.
The organization claims that generated randomness was evaluated using recognized frameworks, including BSI AIS 20/31 and the NIST SP 800-22 test suite.
The system also carries EAL 3 and PTG 3 classifications, reflecting compliance with security requirements set by Germany’s Federal Office for Information Security.
Unlike many software-based approaches, the platform relies on physical quantum phenomena rather than mathematical procedures intended to simulate randomness.
Rack-mounted hardware and cloud access offer deployment flexibility
Fraunhofer IPMS offers the technology through both dedicated hardware and cloud-based delivery models to meet various operational requirements.
The primary hardware version comes as a 19-inch rack-mount unit intended for deployment in data centers and other controlled computing environments.
The device combines quantum entropy generation, signal acquisition, randomness extraction and system integration within a single platform with 10 Gbit/s Ethernet connectivity.
Fraunhofer IPMS said the development process remained entirely in-house, covering optical subsystem design, low-noise analog electronics, high-speed data acquisition and FPGA-based post-processing.
For organizations unwilling 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 practical and accessible,” says Alexander Noack, Division Director Data Communication and Computing at Fraunhofer IPMS.
“Whether it’s a robust 19-inch rack system integrated into your own infrastructure or via our online Entropy-as-a-Service platform, we remove the barriers to adopting quantum security.”
Fraunhofer IPMS is now actively seeking partners to pilot the technology and help build practical, real-world applications around it.
Noack added that the goal involves working together to raise the overall bar for security and trust as quantum computing capabilities continue.
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 preparation.
