Idea
We live in an increasingly connected world, where a superior source of entropy is the key to data security. The effectiveness of any cryptographic system is determined by the strength of the keys it used. In turn, the strength of the key is determined by the degree of randomness used in its generation. And Quantum Random Number Generators (QRNGs) leverage the random properties of quantum physics to generate a true source of entropy, improving the quality of seed content for key generation.
BENEFITS OF HAVING A QUANTUM RANDOM NUMBER GENERATOR:
The source of randomness is unpredictable and controlled by quantum process.
The entropy source tends to produce true random output.
Live/ real-time monitoring of entropy source is possible and highly effective as well.
All attacks on the entropy source are detectable.
The above factors indicate that our QRNG is provably secure.
APPLICATIONS OF QUANTUM RANDOM NUMBER GENERATOR:
Securing data at rest in data centres
Securing any kind of sensitive data
Securing data in the cloud
One-time pad for authentication in banking and other transactions
Gaming applications and lottery
Block-chain network
Numerical simulations, statistical research
IoT devices
E-commerce and banking applications
Cryptographic applications
Telecom and 5G
QUANTUM-ENABLED SECURITY AS A ROOT OF TRUST
In today’s Y2Q world, developers have to rely on the source of entropy as quantum-enabled security keys are set to become the new normal. Organisations should, therefore, implement QRNG to protect their customers’ data.
Principles
In cybersecurity, a perfect random number is the root of trust. A QRNG does not rely on mathematical algorithms but on laws of quantum physics to ‘naturally’ generate random numbers.
A QRNG can produce unpredictable outcomes in a robust and well-controlled way. It includes the power of complex deep-tech technologies such as semiconductors, optoelectronics, high precision electronics, and quantum physics that work together to create the highest level of randomness possible.
QRNGs use random properties of quantum physics to generate a true source of entropy. This improves the quality of seed for key generation. Since the entropy sources are derived from fundamental models, all the properties and behaviors are understandable and provably secure.
