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 recipient, public-key ...

PUFFIN offers graphics card breakthrough versus break-in

(Phys.org)—The PUFFIN Project has come up with research that suggests GPU manufacturing processes leave each product with a unique kind of fingerprint. PUFFIN stands for physically unclonable functions found in standard ...

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 ...

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.

The perfect clone: Researchers hack RFID smartcards

Professional safecrackers use a stethoscope to find the correct combination by listening to the clicks of the lock. Researchers at the Ruhr-University Bochum have now demonstrated how to bypass the security mechanisms of ...

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 during the course ...
