| Abstract(in English) | Chaos has the characteristics that small variations of parameters make the results of recursive calculations quite different. In our past studies, cryptosystems used this characteristics on chaostic maps were proposed. These systems had the advantage of its simplicity. However, they had two disadvantages at the same time. One is that the maps used in the systems were piecewise-linear one, the other is that the ratio of the ciphertext size to the plaintext size becomes very large. The former makes the linear attack be possible and the latter makes the information efficioncy be bad. Therefore, in this study we try to overcome the two disadvantages by using two chotic maps in the system. |
