OVERVIEW OF INNOVATION IN DIGITAL SECURITY

Since 2020, Carrousel Digital has been committed to digital security by providing solutions to security flaws that are still overlooked. Carrousel Digital has therefore developed various processes to improve cybersecurity: these processes have been patented, testifying their novelty.

Can you please describe these technics?

They each address a different problem and implement different technologies, sometimes very innovative, sometimes more traditional:
•  The post-quantum vulnerability in electronic signatures is addressed by an electronic signature using one-time keys and no encryption mechanism.
•  The distribution of single-use keys for peer-to-peer use within a community is addressed   by the so-called single-use key distribution patent, allowing network less operations when necessary.
•  the chaining of transactions carried out in offline mode making it possible to trace the history of financial transactions carried out in offline mode and thus allowing them to be checked a posteriori.
•  The security of encryption keys is addressed by a patent relating to an electronic circuit that 'automatically' erases a memory space (containing encryption keys) when the data in another memory space (containing the code of a software) is modified, rendering unusable hardware whose firmware would have been fraudulently uncovered
•  a mechanism for obfuscating a screen, as soon as a spy camera or a second person approaches the screen field of vision is detected, makes it possible to secure the use of PIN codes.
•  A mechanism for transmitting information by entangled photons makes it possible to communicate in post-quantum security by optical fibres or by satellite.
•  an optical router allowing the use of a photonic network for workstations, where a simple fibre connection of said stations to a single optical router suffices.
•  a geolocation system using electromagnetic waves in the range of UHF to longwave, making it possible to geolocate the counterparty of an online transaction or a user, even when indoors.

Can you provide more details on the photon communication?

Carrousel Digital secure communication scheme permits data transmission using entangled photons and quantum secure communication all in one channel. This scheme, can be used, together with our photonic passive router to transmit information using optical fibres.

 

It will be able to bring full quantum encryption to the communication without using any classical encryption technic. The authenticity of the communication is using our Random Hash signature which is also not using any classical encryption technic, therefore bypassing the new weakness brought by quantum computers.

 

We are currently developing a prototype for this system

A more advanced version will then be able to use our passive photonic router that routes the light between its ports according to their colour, without using any active component nor electronics, providing full data security between work stations in an hospital for instance.
