If You Could Use a QRNG, Why Wouldn’t You?


Some thoughts on why everyone should consider implementing quantum random number generation (QRNG) technologies. It is a risk to assume a system generated random number is truly random. Our devices do constant health checks to ensure you are getting a verified number to make your encryption as secure as possible.

In an increasingly interconnected world, data security has become a paramount concern. Encryption plays a crucial role in safeguarding sensitive information, but it is only as strong as the randomness of its cryptographic keys. Weaknesses in encryption algorithms and insufficient randomness in key generation can leave data vulnerable to attacks. However, by installing a hardware Quantum Random Number Generator (QRNG), these risks can be effectively mitigated. This article explores the advantages of implementing a hardware QRNG, emphasising its ability to strengthen encryption, it’s affordability, and the importance of openness and transparency in security devices.

1) Strengthening Encryption through a Hardware QRNG:

Encryption algorithms rely on the generation of random numbers, known as cryptographic keys, to secure data. However, traditional pseudo-random number generators (PRNGs) used in software-based encryption solutions are deterministic and can be vulnerable to attacks if the seed value is weak or compromised. By contrast, a hardware QRNG utilises the inherent unpredictability of quantum physics to generate true randomness. This randomness ensures that the cryptographic keys are not susceptible to predictable patterns or biases, significantly enhancing the security of encryption algorithms. Installing a hardware QRNG helps overcome the limitations of weak seed values and strengthens the foundation of encryption.
Current technology for TRNG devices is from the 70’s and there is a limit on the entropy generation that can be achieved. This puts limitations on the generation of the keys and necessitates the use of a PRNG to expand and generate keys from the same Random Number by expanding with a counter. These are outdated technology problems that a QRNG solves.

2) Affordability: A Critical Factor for QRNG Adoption:
While the benefits of a hardware QRNG are evident, cost considerations are crucial for widespread adoption. For original equipment manufacturers (OEMs), the cost of implementing a QRNG must not exceed the value of the devices they are being installed in. Recognising this, QRNG technology has advanced to the point where the cost of integration is minimal. By ensuring that the cost is sufficiently low, QRNG becomes an economically viable solution for OEMs, removing the barrier to adoption and making it an attractive proposition for enhancing the security of their devices.

3) Openness and Transparency in Security Devices:
When selecting a QRNG partner, openness and transparency should be primary considerations. It is essential to choose a solution that utilises easily available, off-the-shelf components and readable embedded code. This approach enables third-party verification and scrutiny, ensuring that the QRNG operates as intended and eliminates potential vulnerabilities or backdoors. By leveraging established components and readable code, users can have confidence in the reliability and integrity of the QRNG implementation. Openness and transparency form the foundation of trust, assuring users that their data remains secure and that the QRNG operates with integrity.

4) Summary: Embracing Technology for Enhanced Security:
In a world where data breaches and cyber threats are ever-present, organisations must leverage available technologies to fortify their encryption practices. Installing a hardware QRNG provides a cost-effective solution that addresses the inherent weaknesses of encryption algorithms and PRNGs. By overcoming the vulnerability of weak seed values, a QRNG significantly enhances the randomness of cryptographic keys, making them more resistant to attacks. Moreover, the affordability of QRNG integration and the importance of openness and transparency further strengthen the case for its adoption.

In conclusion, with technology evolving at a rapid pace, it is crucial to employ every available measure to maximise data security. Implementing a hardware QRNG from a reputable provider, such as Crypta labs, ensures that encryption is as secure as possible. By eliminating weak seed vulnerabilities, providing an affordable solution for OEMs, and emphasising openness and transparency, a hardware QRNG becomes an essential component for enhancing data security. In a world where the stakes of data protection are high, it is wise to take advantage of the advancements in technology to safeguard sensitive information.
