A team of researchers has published a paper showing “perfect secrecy cryptography” on a chip. The technique is resistant to even quantum computer exploitation because it uses correlated chaotic wavepackets, which are mixed in inexpensive silicon chips. The paper says the second law of thermodynamics and the exponential sensitivity of chaos unconditionally protect this scheme. It is notable because it can be implemented using low-cost, standard hardware components. The researchers say the scheme is unbreakable and resistant to quantum computing exploitation.”]
