True Random Number Generator Market Set to Reach USD 9.19 Billion by 2032
The True Random Number Generator (TRNG) market is projected to grow significantly, reaching an estimated USD 9.19 billion by 2032, according to a report from SNS Insider. The market, valued at USD 4.02 billion in 2024, is expected to expand at a compound annual growth rate (CAGR) of 10.98% from 2025 to 2032, driven by increasing demands for secure encryption and data protection in various sectors.
One of the key factors contributing to this growth is the rising need for robust security solutions in the face of escalating cyber threats and the advancements in quantum computing. Unlike deterministic processes, TRNGs utilize unpredictable physical or quantum phenomena, which provide higher entropy levels essential for secure communications and encryption algorithms. As industries adopt more interconnected digital infrastructures, sectors such as finance, defense, and the Internet of Things (IoT) are increasingly reliant on TRNGs.
Market Drivers and Segmentation
The demand for TRNGs is further supported by the evolution of quantum computing, the integration of technology at the edge, and regulatory frameworks focused on data privacy. As investments in research and development increase, miniaturized quantum hardware is positioning TRNGs as crucial components of future security architectures and scalable digital ecosystems.
In terms of market segmentation, the Free-Running Oscillator (FRO) segment led the revenue share in 2024, accounting for 41% due to its lower costs and simple architecture. This makes FRO-based TRNGs particularly well-suited for IoT and consumer electronics. Looking ahead, the quantum random number generator (QRNG) segment is expected to exhibit the fastest growth, projected at a CAGR of 11.98%, due to its superior entropy quality and suitability for high-security applications.
By application, the cryptography and cybersecurity sector held the largest share in 2024, representing 47% of the market. This growth is attributed to the increasing need for secure encryption and key generation as cyberattacks become more sophisticated. The IoT and embedded systems segment is anticipated to grow rapidly, with a CAGR of 11.85% from 2025 to 2032, as TRNGs offer secure cryptographic solutions for resource-constrained devices.
Regional Insights and Future Outlook
Regionally, North America dominated the TRNG market in 2024 with a 37% market share, fueled by strong demand in cybersecurity, finance, and defense sectors. The region’s technological maturity and investments in quantum encryption technology have bolstered this position. Meanwhile, the Asia-Pacific market is projected to grow at the fastest rate, with a CAGR of 11.89% through 2032, driven by advancements in electronics manufacturing and the development of secure IoT technologies.
Europe also presents significant potential for market growth, driven by regulations such as the General Data Protection Regulation (GDPR) and investments in post-quantum cryptography. In Latin America and the Middle East & Africa, steady growth is observed, supported by increasing digitalization and government initiatives aimed at enhancing cybersecurity.
Recent developments in the industry include a strategic partnership formed in November 2024 between Infineon Technologies and Quantinuum, aimed at co-developing advanced ion trap technology for quantum computing, which indirectly relates to the development of TRNG systems.
As organizations continue to seek high-quality entropy and secure cryptographic solutions, the TRNG market is poised for significant expansion over the coming years. With continuous technological advancements and increasing awareness of cybersecurity threats, TRNGs will play an essential role in fortifying sensitive data across various sectors.
