Public key attack on knapsak PKC based on subset sum decision problem
Ryuichi Sakai, Yasuyuki Murakami (Osaka Electro-Communication Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In 2012, Murakami, Hamasho and Kasahara have proposed a knapsack PKC based on the subset sum decision problem. An attack against these type of knapsack PKCs by computing alternative solutions of the knapsack problem is then proposed by Nagao and Morii. In 2016, one of the authors, Murakami, have also proposed the knapsack type PKC (M16 PKC) based on the subset sum decision problem for preventing Nagao and Morii attack.
In this paper, we propose the new effective attacks against M16 knapsack PKC. The proposed attacks are able to compute equivalent secret key from the public key, and decode the cipher text of M16 PKC with the equivalent secret key, in a same way of the decryption with the legitimate ecret(decryption) keys.
