Description: Cryptanalysis and the standardization of cryptographic algorithms require significant time and effort for their security to be trusted by governments and industry. ETSI is taking a proactive approach to defining the standards that will secure our information in the face of technological advance.

The advent of large-scale quantum computing offers great promise to science and society, but brings with it a significant threat to our global information infrastructure. Public-key cryptography - widely used on the internet today - relies upon mathematical problems that are believed to be difficult to solve given the computational power available now and in the medium term.
However, popular cryptographic schemes based on these hard problems – including RSA and Elliptic Curve Cryptography – will be easily broken by a quantum computer. This will rapidly accelerate the obsolescence of our currently deployed security systems and will have dramatic impacts on any industry where information needs to be kept secure.
Quantum-safe cryptography refers to efforts to identify algorithms that are resistant to attacks by both classical and quantum computers, to keep information assets secure even after a large-scale quantum computer has been built.
