Abstract (in Japanese) (See Japanese page) 
(in English) In this paper we present three new schemes for augmenting the conventional code-based PKC(CBPKC), product-sum type PKC($SigmaPi$PKC) and the multivariate PKC(MVPKC).
The conventional CBPKC is in general insecure against ciphertext attack. $SigmaPi$PKC is insecure against the secret key attack and LLL attack.
MVPKC is insecure against Gr$ddot o$bner bases attack, rank attack and LLL attack.
We show that with the proposed augmentation schemes, K(AI)Scheme, K(Aii)Scheme and K(Aiii)Scheme, the securities of the conventional CBPKC $SigmaPi$PKC's and MVPKC's would be much improved.
