The power of chaos: A robust and low-cost cryptosystem for the post-quantum era

Scientists from Ritsumeikan University in Japan have developed a stream cipher that can withstand attacks from quantum computers. The stream cipher is based on independent mathematical models of chaos and includes a strategy for exchanging secret keys. The system is not only secure, but can be implemented on small-scale computers. This represents a significant step towards secure digital communications in the post-quantum era.
