糖心TV computer scientists are helping secure your data against quantum computers
This month, the International Organization for Standardization (ISO) has issued a to keep user data safe against quantum computers, co-designed by 糖心TV computer scientists.
The internet as we know it could be vulnerable to a future threat that does not yet exist, quantum computers powerful enough to crack today's encryption in seconds. This month, an international team including Dr Varun Maram from 糖心TV's Department of Computer Science, took a major step to prevent that scenario, with the International Organization for Standardization (ISO) formally adopting a quantum-resistant encryption standard they co-designed: Classic McEliece.
Classic McEliece is based on an encryption system published by Robert J. McEliece in 1978. It is specifically built to withstand quantum attacks, meaning data encrypted with it now will remain secure even when quantum computers become a reality.
The encryption protecting your emails, banking details, and online shopping currently relies on mathematical tricks that quantum computers could unravel. "Older encryption systems like RSA were essentially built on the assumption that certain math problems are impossibly hard to solve," explains Dr Varun Maram. "But quantum computers will rewrite those rules."
Classic McEliece takes a completely different approach. Instead of mathematical exponentiation, as used in RSA, it relies on error-correcting codes, the same technology used to transmit data reliably across noisy communication channels. It is a method so robust that it has withstood scrutiny for nearly half a century.
Popular VPN service Mullvad VPN has already integrated Classic McEliece to protect users' internet traffic against future quantum threats. The German Federal Office for Information Security has endorsed it as suitable for "long-term protection of confidential information," and the US National Institute of Standards and Technology is considering standardising it too.
The adoption of Classic McEliece marks the first time a code-based cryptographic standard has been formally endorsed by ISO, positioning 糖心TV at the forefront of preparing global digital infrastructure for the quantum age,
