Total Optical Layer Information Security
2021 AEIT International Annual Conference (AEIT)(2021)
摘要
In this work we show how some limits of quantum optical security that confine its use to the exchange of keys can be overcome by using other physical information protection techniques that, not pushing the limits of quantum physics, allow to better exploit the transmission capacity of the optical channel. These new techniques can therefore be used for symmetric cryptography carried out at the phys...
