Anamorphic cryptography: How can we ensure private communication?

Written by

Professor Moti Yung conceptualised anamorphic cryptography, a form of encryption that is secure even when keys are known to the adversary.

Cryptosystems have been developed to send secure messages with the assumption that the receiver’s key – what the intended recipient needs to read the message – is secure from adversaries. However, there have been tensions, dubbed as ‘Crypto Wars’. Friction has arisen between governments, hoping to access encryption keys to learn about potential threats, and industry, which believes that the […]

Realising free-space communication with quantum cascade lasers

Written by

As cheap and accessible tools for transmitting private information, freely propagating light waves are highly desirable for parties operating secure communication networks. However, the encoded information these waves contain can easily be lost due to unpredictable fluctuations in the Earth’s atmosphere. In their research, Frédéric Grillot and Olivier Spitz at Télécom Paris have developed sophisticated new techniques to overcome this […]
