| Abstract(in English) | Cryptosystems use many random numbers ; In block ciphers, each communication pair must generate and keep secret key (random number) and in ElGamal-type public ley cryptography (or signature) system sender of message (or signature) must generate and keep secret random numbers of about 300 decimal digits for individual messages (or signatures). This is not an easy work in general. This paper presents a simple method for generating many large (e.g., 30_300 decimal digits) random numbers by computing chaotic wequences {x_n}(n≧0) taking values 0≦x_n≦1 such as logistic chaos and tent chaos, using floating-point functions of GNU GMP with enough significant digits and reading specified digits of x_n as a positive integer random number for discrete ns. If the initial value x_0 is kept secret, this method can be made secure due to the chaos property of sensitive dependence on the initial value. Some effective applications are also discussed briefly. |
