1. What is it?QuantaSEC

2

• The KeyBITS Platform generates and distributes UNLIMITED SEQUENCES of truerandom bits between users A and B, in a fast and secure way.

• It uses an optical channel for key distribution. It uses photon numbers in a mesoscopic range.

• Speeds above 1GHz.• Achieves a transmission distance of ~700 𝑘𝑚 using optical amplification.

Working principles were evolved from the encryptionsystem "alpha-eta“ developed with support from DARPA(Northwestern University/Telcordia/BBNT).

Partnership is needed to develop the optical modulation/demodulation system for the TX and RX stations.(Known and straightforward technology)

The Physical Random Generator (PhRBG) prototype was supported by the Brazilian Ministério da Ciência, Tecnologia e Inovação (MCTI)- Finep(0276/12)-Fundep(19658)-Army Command (DCT)-RENASIC.Down-sizing of the PhRBG is possible.

FlexibilityQuantaSEC

o The physical principles used do not restrict the speed therefore technological

advances can be incorporated to increase speed.

o Use of FPGA may allow an easier integration to the needs of IoT (Internet of

Things) and IIoT (Industrial Internet of Things).

o The actual system uses commercial components for faster development.

o Several services may be developed around the keyBITS Platform.

Noisy channel performs the key distributionEncrypted signals are sent by comercial fibers or other “noiseless” channels

4. Light ProtectionQuantaSEC

For an overall view of the light protection on the transmitted signals see arXiv:1406.1543v2 [cs.CR] 8 Jul 2015.

It uses a noisy optical channel to hidden the signals sent from a to B plus a Privacy Amplification

Protocol. The security level is information-theoretically calculated and shown to be negligible.
