The new frontier in online security: Quantum-safe cryptography

A team of experts led by Monash University researchers, in collaboration with Australia's national science agency CSIRO, has created an algorithm that can help strengthen online transactions that use end-to-end encryption against powerful attacks from quantum computers.

Cryptography researchers from Monash University's Faculty of Information Technology and CSIRO's data and digital specialist arm Data61 have developed the most efficient quantum-secure cryptography algorithm, called "LaV," to enhance the security of end-to-end encryption, with potential application across instant messaging services, data privacy, cryptocurrency and blockchain systems.

Cryptography

From Greek κρύπτω krýpto "hidden" and the verb γράφω gráfo "to write" or λέγειν legein "to speak". Cryptography is the practice of establishing a secure connection between two parties in the presence of a third party whom you don't want to be able to read your messages. Cryptographers design algorithms and protocols, which do exactly this (and many other things). They also use a lot of time looking for security holes in existing protocols to make sure they can still be trusted. This is called cryptanalysis.
