True Random Number Generator (TRNG) Market Size is valued at USD 3.5 Bn in 2024 and is predicted to reach USD 14.7 Bn by the year 2034 at a 15.6% CAGR during the forecast period for 2025-2034.
A True Random Number Generator (TRNG) is a device or system that generates random numbers from a physical process, such as radioactive decay, thermal noise, or atmospheric noise, rather than a deterministic algorithm. Unlike pseudo-random number generators (PRNGs), TRNGs rely on inherently unpredictable natural phenomena, ensuring high entropy and true randomness. They are critical in applications like cryptography, secure communications, and simulations where unbiased, unpredictable numbers are essential.
The market for genuine random number generators is being propelled by the increasing demand for strong security solutions in sectors such as defence, banking, and cybersecurity. The need for trustworthy encryption is growing as businesses move to networked settings, and TRNGs are crucial for safe data transfer. TRNG use is pushed by the growing importance of quantum-safe encryption, which is further highlighted by the development of quantum computing.
In addition, TRNGs are used by the finance industry to avoid fraud and by the healthcare industry to encrypt electronic health records. The market expansion and broad use of genuine random number generators are fueled by these considerations taken together.
The True Random Number Generator (TRNG) market is segmented based on type, application, vertical, and end-user. Based on type, the market is segmented into noise-based TRNG, chaos-based TRNG, free-running oscillator-based TRNG, and quantum-based TRNG. The segment application, includes security & cryptography, simulation & modelling, data processing, networking, and others. By vertical, the market is segmented into IT & telecom, consumer electronics, BFSI, government & defence, automotive, healthcare, retail & e-commerce, and others.
The free-running oscillator-based TRNG category is expected to hold a major global market share in 2021 because of its scalability, affordability, and ease of integration. They create genuine randomization in semiconductor devices by using electrical noise, including flicker or thermal noise. Their suitable choice stems from their ease of integration into FPGAs, ASICS, and SoCs—all of which are common in cryptographic usage and safe key generation. Because FRO-based TRNGs are efficient and have low power consumption, leading semiconductor companies like ARM, Intel, and AMD favour them for use in server-class computing, consumer electronics, and loT devices.
The true random number generator market is dominated by security and cryptography applications because of the increasing demand for robust cybersecurity solutions in an increasingly digital and linked world. TRNGs are crucial for cryptographic applications because they offer a source of genuine randomness for generating cryptographic keys, nonces, and initialization vectors—all of which are necessary for protecting encryption techniques, authentication methods, and communication protocols.
The North American True Random Number Generator (TRNG) market is expected to register the highest market share in revenue in the near future, fueled by rising demand in the telecom, financial services, and aerospace industries. Strong cybersecurity laws and a well-established semiconductor sector assist the area by promoting the use of hardware-based security measures. Partnerships between public and commercial tech companies have hastened the development of cutting-edge TRNG technology.
In addition, Asia Pacific is projected to grow rapidly in the global True Random Number Generator (TRNG) market driven by large expenditures in electronics manufacturing, cybersecurity, and digital infrastructure. In China, Japan, India, and South Korea, the fast urbanization and smart city initiatives are driving the demand for secure communication hardware. Additionally, quantum research initiatives in the public and business sectors are promoting the creation of small and affordable TRNG technology.
