Twisted light waves sent across Vienna
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna.
New approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
GSM system about to be compromised
Heartbleed bug find triggers OpenSSL security advisory
Toshiba researchers achieve new record bit rate for quantum key distribution
The Cambridge Lab of Toshiba Research Europe today announced a major breakthrough that will allow ultra-secure encryption of sensitive data sent by banks, hospitals and government organisations.
Beefing up public-key encryption
Most financial transactions on the Internet are safeguarded by a cryptographic technique called public-key encryption. Where traditional encryption relies on a single secret key, shared by both sender and ...
PUFFIN offers graphics card breakthrough versus break-in
Towards 'unbreakable' message exchange
Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks.
Physicists successfully transmit secure quantum code through atmosphere from aircraft to ground station
(Phys.org) —Can worldwide communication ever be fully secure? Quantum physicists believe they can provide secret keys using quantum cryptography via satellite. Unlike communication based on classical bits, ...
Making quantum cryptography truly secure
Quantum key distribution (QKD) is an advanced tool for secure computer-based interactions, providing confidential communication between two remote parties by enabling them to construct a shared secret key ...
Perfecting email security
Millions of us send billions of emails back and forth each day without much concern for their security. On the whole, security is not a primary concern for most day-to-day emails, but some emails do contain personal, proprietary ...
