Description

[0001] This invention discloses a true random number generation device based on the interval continuous principle that supports national cryptographic security. It belongs to the fields of national cryptographic applications, information security encryption, and domestically produced cryptographic hardware technology, and fully complies with the national cryptographic industry standards GM / T0005-2021 "Randomness Detection Specification," GM / T 0078-2020 "Design Guidelines for Cryptographic Random Number Generation Modules," and GM / T 0103-2021 "Overall Framework of Random Number Generators." This device is based on the interval continuous physical entropy change principle, equipped with a domestically produced GZ-Crypto-RISC-V cryptographic chip and the RandomCheck-AI randomness intelligent verification model. It consists of a continuous interval physical entropy source module, an interval state acquisition unit, a STE encoding and quantization unit, a randomness verification unit, and a national cryptographic standard output interface unit. The core quantization thresholds are set as follows: minimum entropy ≥ 0.9998 bit / bit, random number generation rate ≥ 1Gbps, generation delay ≤ 1μs, randomness detection pass rate 100%, periodic length ≥ 10^12 bits, and **unreproducibility rate 100%**. By constructing a continuous, uninterrupted, aperiodic, and unpredictable physical entropy change range, multi-point synchronous high-speed acquisition of entropy source signals is achieved. These signals are then converted into a national standard binary random sequence via domestically produced STE encoding and quantization. AI-based multi-dimensional real-time randomness verification is then used to eliminate abnormal deviations before outputting highly secure true random numbers. This device features a purely domestic hardware architecture, with no reliance on foreign chips, algorithms, or architectures, and no security backdoors. Its randomness, stability, and attack resistance far surpass those of pseudo-random number generators. It can fully support high-level national cryptographic security scenarios such as government encryption, financial cryptography, communication confidentiality, and data security, providing underlying core random number support for key generation, identity authentication, and data encryption. Technical Field

[0002] This invention belongs to the fields of national commercial cryptography, information security encryption, hardware true random number generation, domestically produced cryptographic chips, and critical information infrastructure security technology. Specifically, it relates to a true random number generation device based on the interval continuous principle that supports national cryptographic security. It is particularly suitable for high-level, high-reliability, and independently controllable national cryptographic security scenarios such as government cryptographic machines, financial encryption terminals, communication security equipment, data security platforms, and cryptographic modules of critical information infrastructure. It strictly follows the various commercial cryptographic standards of the State Cryptography Administration. Background Technology

[0003] Current random number generation technologies in the field of national cryptographic security have many fatal shortcomings and cannot meet the rigid requirements of high-level cryptographic security: First, mainstream pseudo-random number generators are based on algorithm iteration, which has the risk of fixed patterns, periodicity, predictability, and reversibility. Once the algorithm is cracked, the entire cryptographic system is completely invalidated and cannot be used in critical national cryptographic scenarios. Second, existing physical true random numbers mostly rely on single entropy sources such as thermal noise, noise diodes, and oscillator jitter, which are easily affected by temperature, voltage, and electromagnetic environment interference. They lack randomness, uniformity, and unbiasedness, fail to meet minimum entropy standards, and exhibit periodicity. Third, the entropy source signal is discrete and discontinuous, with low entropy density and slow random number generation rate, making it unsuitable for high-speed encryption scenarios; fourth, the core random number generation architecture, chip, and verification algorithm all rely on foreign technology, posing risks of hidden backdoors, data leakage, and malicious control, resulting in extremely poor domestic self-control and violating national requirements for independent control of cryptographic security; fifth, the lack of a real-time multi-dimensional randomness verification mechanism means that abnormal entropy sources cannot be eliminated in a timely manner, leading to deviations in the output random numbers and making it difficult to pass the randomness detection standards of the State Cryptography Administration, severely restricting the construction of the national cryptographic security system.

[0004] To address the aforementioned technical challenges, this invention constructs a novel physical entropy source based on the principle of interval continuity. By combining domestically produced dedicated chips with AI intelligent verification, it creates a true random number generation device that is aperiodic, unpredictable, unreproducible, and highly resistant to interference. The entire process complies with national cryptographic standards, achieving 100% independent control. Summary of the Invention
