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 […]

Secret Manhattan Project ciphers finally solved

Written by

Paul Relkin has broken the code of the decades-old Olum ciphers, and in the process developed a novel cryptanalysis method for decrypting transposition ciphers.

While working on the creation of the world’s first atomic bomb, mathematician Paul Olum challenged his colleague, the distinguished theoretical physicist Richard Feynman, to solve his two ciphers – Olum 1 and Olum 2. Feynman failed, and the ciphers went unsolved for more than 75 years. Paul Relkin, an American software developer and cryptanalysis enthusiast, has recently published the first […]
