| Outline of Final Research Achievements |
This study is concerned with an integrated chaos-based stream cipher consisting of a pseudorandom number generator based on a large-scale chaotic map, a method for exchanging a secret key with randomized coupled chaotic oscillators, a logistic hash function to confirm the identity of the exchanged secret keys. We performed an experiment of the secure communication of image data and found that the encryption and decryption of the data were performed within a practical time. The present results indicate the applicability of our stream cipher to practical secure communications.
