Quantum Random Number Generators (QRNGs) provide physically unpredictable entropy essential for cryptography, modeling, and scientific research. Local generation is preferred for the highest level of security, as it eliminates the risks associated with transmitting data over a network. At the same time, public QRNG web services accessible via the API serve as a valuable tool in cases where dedicated hardware is unavailable, enabling rapid integration into software prototypes, statistical testing, large-scale simulations, and educational projects. Combining local and remote sources makes it possible to optimize the balance between security, accessibility, and performance. This article helps to develop and justify a typical QRNG web service infrastructure, which includes functional components, security requirements, access interfaces (API), methods for quality control of randomness, and recommendations for scalability. The proposed infrastructure is intended to serve as a foundation for creating interoperable, secure, and efficient web services of quantum entropy sources.

Quantum Random Number Generators (QRNG), based on physical processes of quantum mechanics, provide a high level of entropy and unpredictability, making them a promising source of randomness for use in information and communication systems, particularly in the context of post-quantum cryptography. However, using the QRNG in the format of a web service (e.g., via public APIs or cloud platforms) introduces new attack vectors that may compromise the trust in the generated data. This work develops a threat model and an offender model for a QRNG web service. The methodological foundation of the study is based on modern risk analysis standards, including the ISO/IEC 27005, STRIDE, and Common Criteria. Critical system assets are identified, potential threats are classified considering the specifics of quantum generation, and an offender profile is constructed. Typical attack scenarios are considered, including random number interception, physical generator compromise, API service attacks, and insider threats. For each scenario, a risk assessment is performed based on the likelihood of occurrence and potential consequences. A comprehensive set of protection measures is proposed, including technical (TLS, post-processing, monitoring), organizational (access control, auditing), and procedural (incident response)solutions. The results of this work can be used to develop secure QRNG services integrated into critical cryptographic systems and serve as a basis for further research in the field of quantum technology security modeling.
Web services of quantum random number generators (QRNG) open new opportunities for enhancing the resilience of cryptographic systems due to their ability to generate true random numbers based on quantum effects. Unlike pseudo-random number generators (PRNG), the QRNG ensures a high level of unpredictability in output data, making them critical components in modern security systems. However, their implementation is accompanied by significant challenges, particularly due to potential attacks at the software level and during integration with hardware infrastructure. At the software level, major threats include attacks on cryptographic libraries, substitution or manipulation of runtime output data, and side-channel attacks exploiting information leaks from physical number generation processes. At the hardware level, risks arise from equipment defects, failures in integration processes, or improper operation of the QRNG in combination with other systems. This study provides a classification of the main types of attacks on QRNG web services, presents an analysis of existing attacks, and introduces modern approaches to their prevention. Among the key solutions are the certification of the QRNG during development and deployment, multi-factor verification of output data to ensure unpredictability, and the use of monitoring systems with artificial intelligence algorithms for anomaly detection. Special attention is given to hybrid protection methods that combine the QRNG with quantum key distribution (QKD) and post-quantum cryptographic algorithms, allowing for the mitigation of risks from both classical and quantum attacks. Thus, a comprehensive combination of software and hardware security methods will enhance the reliability of QRNG and their resilience to modern threats. Further research should focus on the implementation of unified standards for QRNG and the optimization of their integration into existing cryptographic systems.
Quantum random number generators (QRNG) provide quality random numbers, which are essential for cryptography by utilizing the unpredictable nature of quantum mechanics.Advancements in quantum optics made multiple different architectures for these possible.As part of a project aiming to realize a QRNG service, we developed a system capable of providing real-time monitoring and long term data collection while still fulfilling regular processing duties for these devices.In most cases, hardware validation is done by simply running a battery of statistical tests on the final output.Our goal, however, was to create a system allowing more flexible use of these tests, realizing a tool that can also prove useful during the construction of our entropy source for detecting and correcting unique imperfections.We tested this flexibility and the system's ability to adequately perform the required tasks with simulated sources while further examining the usability of available verification tools within this new custom framework.
Truly random integers, which are the absolute requirement for this type of cryptography, are necessary for data security. Conventional PRNGs is deterministically which makes them predicted. This type of weakness is present in them. Unlike conventional algorithms, QRNG uses something very fundamental, quantum physics. It has allowed for a breakthrough in using random numbers that are unpredictable. The main goal of the project to design a system including the QRNG (quantum random number generator) and cloud platform developed by IBM. The system produces robust and ideal output for cryptography while being both effective and efficient. We will conduct detailed and effective tuning and testing so as to increase output. Outputs of this project are a QRNG system built on the cloud that can be connected with cryptographic applications, certified sequence, and informational materials of the organization. With this research of QRNGs synchronized with the IBM cloud platform, we make cryptographic security stronger by using the quantum mechanical method to create truly random numbers. Moreover, QRNGs contribute to the cryptographic applications which are intended to be incredibly secure and of high dependability by providing random numbers to enter the realm of crypto-with very little human participation. Basically, the cloud-based architecture enable systems to scale and possible failure resilience via migrating the workload or storing the data online. Quantum improvements will speed up the process of replacing the currently accepted cryptographic paradigm with something opening new ways of digital communication. This research is about quantum physics, cloud computing, and cryptography, bringing together how these concepts operate, as a result, of the unexpected and secure cryptographic applications.
As quantum technologies advance, the security of popular cryptographic protocols becomes more threatened by the capabilities of Cryptographically Relevant Quantum Computers (CRQCs). In this scenario, Post-Quantum Cryptography (PQC) has become a potential solution to prolong the life of existing Public Key Infrastructure (PKI) systems. However, PQC protocols depend on high-quality randomness for key generation and encapsulation procedures, with the quality of the entropy source potentially having a profound impact on the security of the overall system. In this work, we demonstrate a proof-of-concept enabling the incorporation of Quantum Random Number Generation (QRNG) devices within communication networks using PQC-based Transport Layer Security (TLS).Using open-source cryptographic libraries and commercial QRNG hardware, we demonstrate their use as entropy sources via an Entropy-as-a-Service (EaaS) model. We highlight two particular use cases: a fully virtualized private PKI network and a connection to an external PQC-enabled server. Experimental results show that EaaS QRNG enables real-time entropy monitoring and quality assessment in cryptographic management systems, with negligible impact on TLS handshake time.
One of the solutions to the problem of secure communication is the Quantum Random Number Generators (QRNGs) which generate true randomness based on quantum mechanical principles.QRNGs are different from conventional pseudo random number generator in that they use quantum uncertainty to generate outputs which are very unpredictable.This work attempts to examine different QRNG architectures, study the possible integration of cryptographic frameworks with these architectures and highlight potential vulnerabilities in the integration of cryptographic frameworks with QRNG architectures.Post-processing techniques, i.e.Zero-Phase Component Analysis (ZPCA) and neural network based techniques are also studied to increase entropy and suppress environmental noise in QRNG systems.Key findings show that system jitter models based QRNG architectures are more scalable and less expensive for use in real world applications.Additionally, incorporating cryptographic protocols with the QRNGs endows them with the ability to resist quantum threats, and hence, provide better key distribution in the secure IoT communication frameworks.However, as security problems such as side channel attacks and hardware manipulation are still big issues.It also points out some of the emerging research trends including hybrid QRNG architectures, i.e., QRNG with classical PRNG to increase the entropy rate.As such, the proposed methodologies attempt to enhance QRNG scalability, security, and energy efficiency in cloud infrastructures, in mobile systems and in critical security environments.The advancement of these technologies will assume a crucial function in the advancement of quantum-safe frames for current advanced computerized foundation.
