Researchers at Kyoto University in Japan have definitively demonstrated the strength of a 128-bit digital lock for cybersecurity applications.
The researchers released new data on the Vector Stream Cipher (VSC), which represents the first example of a 128-bit key chaotic cipher with provable security.
"Many theoretical attacks in the past have failed to break it, but until now we hadn't shown definitive proof of security," says Kyoto University professor Ken Umeno.
The researchers conducted several tests, including a method to evaluate the lock's randomness.
The team says the enhanced VSC is not only secure, but also structurally simple, so it requires low memory usage compared to existing technology, which makes it useful for high-density data transmission applications such as 5G mobile networks and 4K television broadcasts.
"Chaotic ciphers have been in use for about 30 years, but before this study we had not expected to find proof of security," Umeno says.
