Abstract(in English) | This paper investigates the problem in constructing RSA cryptosystem over the algebraic number field. Generating the prime ideal, choosing the complete representation class modulo an ideal, and reducing a number to the modulo class are main problems. For the cyclotomic field and the quadratic field, we describe the algorithms for solving these problems. These algorithms make it possible to construct the RSA cryptosystem over the cyclotomic field and the quadratic field. It is shown that breaking the proposed cryptosystem is as intractable as breaking original RSA cryptosystem. Furthermore, we show that the proposed RSA cryptosystem is stronger against the Hastad attack than the conventional system. |
