Парола: Лазерен лъч

Светът се развива, не спи, а прочетеното от мен току-що ми изглежда като взето на заем от 22-ри век...

перфектна идея, това ограничение обаче от 90 км, не ми харесва, дано се преодолее скоро и системата им стане стандарт.

На пресконференция на black hat в Вегас още преди 3 години излезна инженер researcher който вразумително обясни теоретичната база защо технологията квантови суитчове подлежи на Eavesdropping

he researchers at the University of Singapore, however, have managed to go one step further — they’ve developed a method of producing a full exploit of a QKD system that allows for Eve to eavedrop on Alice’s and Bob’s communication — without introducing enough errors to allow her to be detected. Her eavesdropping appeared to be no different from the random background errors that are inevitable in the physical implementation of a QKD system.

Although the researchers were able to infiltrate this system with basically off-the-shelf parts, it’s worth noting that this exploit doesn’t mean that QKD isn’t a viable method of encryption. The researchers themselves suggest several countermeasures, and no doubt other countermeasures will be developed as this research continues. As the researchers themselves note: ”a more pointed question is what problems still lurk unnoticed in the gap between the theoretical description and the practical systems. Just as in classical cryptography, an ongoing search for backdoors is required to build hardened implementations of quantum cryptography for real-world use.”

Quantum cryptography is still in its infancy, but it’s still more than likely the future of encrypted communications once its been further refined and developed.
