| Abstract(in English) | We propose a knapsack cryptosystem choosing encryption keys that is possibly difficult to cryptoanalyze or to apply LLL algorithm of a typical cryptoanalysis algorithm in the linear cipher. This cryptosystem has a plaintext and multiple encryption keys not corresponding with 1:1 each other and chooses appropriate one from some encryption keys. This cryptosystem includes information (handled as noise) not decoded uniformly in addition to the plaintext. Because a cryptoanalyst can identify a position of the noise with only a probability of 1/2 per element of the plaintext vector and can choose correctly the selected encryption key with only a probability of 1/2, a total possible matrix in LLL algorithm becomes an exponential order. |
