Data Security Infrastructure News

Quantum computers and large super-computers are threatening existing digital security infrastructure. Some new process proposed and published as patents by Carrousel Digital allow to circumvent these deficiencies. The weakness of data security infrastructure come from the fact that computer facilities could break the encryption keys used in our IT systems, from communication to websites to login procedures. |
|
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 shall embed a random number in the e-document to be certified, allowing for its signature with a one time key; is 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 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. |
Contrarily to one might think of QKD, our data transmission scheme, can also be organised centrally thanks to a photonic router that connects to all the terminals of a group with only one fibre. Carrousel Digital has also come up with other procedures to secure the use of the above technologies such as secure onetime key storage on memory where encryption keys get systematically erased upon non controlled firmware modification, and also a safe distribution of pairs of one-time keys, using the internet. |

Finally, we have also patented both in the US and France an indoor geo-localisation system that can be an alternative to GPS but that works indoor (as well as outdoor), and that uses ground-based emitters as opposed to satellite-based ones. Contrarily |
tour scheme, existing GPS requires the emitters to be placed on fast moving satellites. Our scheme is also supplemented by a security layer which enables to detect any tempering of the signals that may lead to erroneous calculations.
Our offline security scheme, allowing to store the history of past transactions onto devices beneficiaries of a new transaction allows for offline security of e-cash ; and, implemented with our quantum safe signature for a quantum safe online/offline e-cash. |

Carrousel Digital will be present as a speaker at the DigiGov exhibition at Excel London on the 24th and 25th of September and have a booth where we can further explain our technologies and designs. |
