The True Random Number Generator (TRNG) market is poised for substantial growth in the coming years, fueled by the increasing global demand for robust data security and the rapid proliferation of Internet of Things (IoT) devices. As cyber threats grow in sophistication, and connected systems become more prevalent across industries, TRNGs are emerging as a critical component of next-generation security infrastructures.

The true random number generator market is expected to grow from USD 3.81 billion in 2025 and is estimated to reach USD 7.71 billion by 2030; it is expected to grow at a Compound Annual Growth Rate (CAGR) of 15.1% from 2025 to 2030.

Rising Demand for Cryptographic Security
Unlike pseudo-random number generators, which use deterministic algorithms, AI impact TRNGs generate numbers based on physical processes, such as electronic noise, which are inherently unpredictable. This makes them ideal for cryptographic applications requiring high levels of randomness, including secure key generation, encryption, and authentication.

With organizations facing increasing pressure to safeguard sensitive data against cyberattacks, the adoption of hardware-based TRNGs is accelerating. Sectors such as finance, defense, healthcare, and telecommunications are turning to TRNGs to strengthen their encryption protocols and comply with stringent data protection regulations.

IoT Expansion Drives Market Penetration
The explosive growth of IoT devices, from smart home systems to industrial automation networks, presents new challenges in data integrity and communication security. These devices often operate in distributed, low-power environments, where lightweight, hardware-level security is essential.

TRNGs play a pivotal role in securing IoT ecosystems by ensuring the authenticity and confidentiality of device communication. As IoT adoption expands into smart cities, automotive systems, and critical infrastructure, the demand for TRNGs is expected to grow in parallel.

Emerging Applications and Technological Advancements
Beyond traditional IT security, TRNGs are being integrated into blockchain platforms, AI systems, embedded systems, and quantum-safe encryption protocols. The growing awareness of potential threats posed by quantum computing is pushing industries toward entropy sources that can withstand future cryptographic challenges—where TRNGs have a clear advantage.

Leading semiconductor manufacturers are incorporating TRNG capabilities into System-on-Chip (SoC) and Hardware Security Modules (HSMs) to support real-time applications in edge computing and cloud environments. Advances in quantum-based TRNGs and photonic noise-based generators are also expanding the market's technological frontier.

Regional Outlook and Competitive Landscape
North America currently leads theTRNG industry due to strong investments in cybersecurity, a mature tech ecosystem, and high defense spending. However, Asia-Pacific is expected to register the highest CAGR, driven by rapid digitalization, increasing cyber threats, and the expansion of data-driven applications in emerging economies.

Major players in the TRNG market include ID Quantique, Intel Corporation, Microchip Technology, Infineon Technologies, and Samsung, among others. These companies are investing in R&D to enhance TRNG performance, miniaturization, and integration with mainstream security solutions.

As the digital world becomes more interconnected and security-conscious, True Random Number Generators are set to become foundational to secure communication, data protection, and trust in emerging technologies. With strong tailwinds from cybersecurity needs and IoT adoption, the TRNG market is expected to witness robust and sustained growth through the next decade.
