DNA strands on tiny beads hide and reveal encrypted messages through programmable fluorescence patterns read by flow cytometry.

In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode ...

(Nanowerk News) Metasurfaces, composed of nanoresonator arrays with tailored structure and subwavelength feature size, show the potential of manipulating various degrees of freedom for manipulating ...

AES-256 remains the gold standard for high-stakes data encryption. While other, more lightweight and less-energy-intensive encryption methods do exist, they operate with multiple trade-offs in ...

Eruces Data Security has secured a patent for its three-step encryption and key management scheme, which is designed to lock down data through its lifecycle. The security firm’s so-called Tricryption ...

Security teams are torn between the quest to encrypt everything and the technical feasibility of doing so. The advantage of encryption is that it obscures data, even after a breach, and satisfies ...

Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL’s School of ...

Internet-connected gadgets like light bulbs and fitness trackers are notorious for poor security. That's partly because they’re often made cheaply and with haste, which leads to careless mistakes and ...

The Web's leading standards group proposed two recommendations for encrypting XML data and documents, a key development in the organization's push to standardize technologies crucial to Web services.

New information has shown that one of the more popular security suites available for Android and iOS is so fundamentally compromised, its claims constitute false advertising. That software suite, NQ ...
