| Abstract(in English) | Kasahala and Murakami proposed a new public key cryptosystem which is Called the SHP-II cryptosystem. Recently, we proposed new attacks based on the low-density attack with the LLL algorithm, the concatenated-key attack and the diferential-key attack. In this paper, we shall discuss the security against the concatenated-key attack and the differential-key attack for the SHP-II cryptosystem. |
