QKD: Researchers break "unbreakable" quantum cryptography

Έσπασε και η "άσπαστη" μέθοδος QKD: Μια ομάδα Σουηδοί επιστήμονες ανακάλυψαν έναν τρόπο να σπάσουν κβαντική κρυπτογραφία, μια νέα, προηγμένη αντίληψη για την data using a law of physics.QKD Quantum Cryptography

Quantum cryptography referred to 1970 as an advanced cryptography model based on photon motions for secure data transmission.

Για πολλά χρόνια, οι θεωρητικοί δήλωναν ότι η μέθοδος είναι "άσπαστη", και δεν θα επιτρέπει σε άλλους να παρακολουθούν την κυκλοφορία που κρυπτογραφείται με την μέθοδο quantum key distribution (QKD).

Some companies even started to develop QKD applications that could be commercially available. But to date, they have only been used in test environments.

According to researchers from Linköping University and Stockholm University, there is a gap in quantum encryption. The way ς των παραμέτρων εμπλοκής ενέργειας-χρόνου που βασίζονται οι compromises QKD.

"Με αυτό το κενό ασφαλείας, είναι δυνατό να παρακολουθούμε με την κίνηση χωρίς να μας εντοπίζουν. Ανακαλύψαμε το κενό ασφαλείας με θεωρητικούς υπολογισμούς μας, και οι συνάδελφοί μας στη Στοκχόλμη ήταν σε θέση να το αποδείξουν πειραματικά," αναφέρει ένας από τους ερευνητές, στο επιστημονικό περιοδικό EurekAlert.

In quantum cryptography, both parts send out a photon at exactly the same time, but there is also a small phase shift from either side. If there is someone who wants to intercept, it creates noise in the communication channel, and the phase shift is shorter. If there is no danger, the photons use the phase shift itself as an encryption key.

In their tests, researchers found that the integrity of the data can only be ensured if both parties communicate with each other using photons rather than traditional light sources.

Scientists have published their findings with a great deal of detail online on the free ScienceMag portal, along with two mitigation techniques that can be used to avoid data destruction.
