Abstract (in Japanese) (See Japanese page) 
(in English) A new signature scheme of MPKC is proposed.
It is created by perturbing a traditional encryption scheme in two ways.
Although this new signature scheme has a structure very difficult to tract, it is fast in signing a message. Along with the security against algebraic attacks, its security against existing attacks is discussed.
The experimental data implies that the scheme can create a both lightweight and secure signature system.
