Abstract (in Japanese) (See Japanese page) 
(in English) In 1990, Murakami and Kasahara proposed an ID based non-interactive key-sharing scheme (MK scheme) that uses the discrete logarithm problem with composite number as the modulus. This is a key-sharing scheme that eliminates the need for preliminary communication. Unfortunately, the MK scheme could not be realized due to insufficient computer performance at the time. In SITA2022, Miki et al. proposed a scheme in which the prime factors of p − 1 and q − 1 are B-smooth, and showed that the MK secret key can actually be obtained. In this research, we propose a method to securely compute the private key of the MK scheme based on the discrete logarithm problem over a composite number of B-smooth order by using secure computation.
