Increasing Edge Computing Security with Quantum Random Number Generators

The journey to the Cloud in highly distributed environments is enabled by Edge Computing. It provides clear management and control advantages, but also comes with security challenges, especially when we talk about critical infrastructures. Cryptography science comes to help in securing communications and the local information. Random number generation is fundamental to any cryptographic system and the only know source of randomness in nature is the quantum realm, therefore Quantum Random Number Generation is the practical solution for supporting the entire cryptographic systems.

The journey to the Cloud is a trend that almost all verticals and sectors initiated some time ago, including now some of the most regulated sectors that traditionally are reluctant to these radical technological changes. But this journey is not easy when we deal with highly distributed environments. Energy distribution, water distribution and treatment, etc. are in addition critical industries with superior security requirements. 

Here is where Edge Computing comes to enable the processing and storage of information locally to the distributed locations while providing a central management and control that permits the execution of the Cloud concepts. 

At the same time, this model creates some security challenges that are more important considering the geo-political context. Secure communications with centralized management but also intra-location communications and storage are of capital importance, and cryptography science gives his hand to help. 

The generation of random numbers is fundamental to any cryptographic system. Used to create keys to encrypt content and communications, create initialization vectors, nonces, certificates, among others, true random number generation make any crypto system secure when we know everything about it except the keys themselves. The only known source of randomness in nature is the quantum realm, therefore Quantum Random Number Generation is the practical solution for the creation of the required randomness that supports the entire cryptographic systems.
