Data Security and Energy innovation

Quantum computers and large super-computers are threatening existing digital security infrastructure. Some new patented a process proposed by Carrousel Digital allow to circumvent these deficiencies. The weakness of data security infrastructure comes from the fact that computer facilities could break the encryption keys used in our IT systems, from communication to websites to login procedures.
On the energy side, Carrousel Digital sister company Marbeuf Conseil et Recherche has come up with heat recycling of hydrogen fuel cells to enable full energy conversion into electricity. The process uses preferably high-temperature solid oxide fuel cells which generate heat above the temperatures required by the Sulfure-Iodine cycle to generate hydrogen in a cycle of endothermic chemical reactions. This patented scheme may also open the way to electric generation out of ambient heat as one of the endothermic reactions works at 120°C which could be reached by elevating heat temperature with heat pumps. |

Carrousel Digital has come up with some patented schemes to overcome this weakness. The two main schemes allow, for one, secure signatures; for the other one : secure data transport. Those schemes are made available through licensing.
The safe signatures scheme should embed a random number in the e-document to be certified, allowing for its signature with a one-time key, i.e. a secret used only once and that can not be recomputed. |

The safe data transmission scheme uses photons to transport the information, coding many bits on each photon and making sure the photons have not been copied or hijacked during transportation. This process is a step further to Quantum Key Distribution (QKD) as it completely avoids the use of key-based encryption and encodes the information on photons, as opposed to solely generating random numbers. It can also use the quantum-safe signature scheme to avoid the man in the middle attack to which non-quantum-safe QKD schemes are vulnerable. |
Carrousel Digital has also come up with other procedures to secure the use of the above technologies, such as secure one-time key storage on memory where encryption keys get systematically erased upon non-controlled firmware modification, and also safe distribution of pairs of one-time keys, using the internet. Contrarily to one might think of QKD, our data transmission scheme can also be organized centrally thanks to a photonic router that connects to all the terminals of a group with only one fiber, whereas QKD, so far, had to use a direct optical fiber between each member of the group. |

The data transmission scheme is fault-tolerant, allowing for data loss in the optical fibers, optical components and free space, allowing transmission, for instance, up to 100 km through optical fibers, or through low orbit satellites.
Our one-time key distribution system allows for practical local storage of one-time keys that can be renewed, enabling data security for offline data transfers, which are |
device-to-device transfers ; therefore providing a means for securing e-cash : cash on a card, and e-identity systems that can be resilient to network faults.
Finally, we also have a patented and indoor geolocation system that can be an alternative to GPS but that works indoors (as well as outdoors), using ground based emitters as opposed to satellite-based ones and that can be used, for instance, to locate the receiving party of a cash transaction. |
