Secret-Key Exchange Through Synchronization of Randomized Chaotic Oscillators Aided by Logistic Hash Function

We have developed a method of secret-key exchange assisted by a secure hash algorithm for a stream cipher based on the augmented Lorenz map as a high-dimensional chaotic map. Two legitimate users are assumed to possess chaotic oscillators subject to the original Lorenz equations to exchange randomized chaotic signals. The oscillators achieve perfect synchronization and generate a sequence of binar...
