dc.description.abstract在本文中,我們將研究LCL和未定性數字表示法(NNR)的可能組合方法,在 這裡我們提出了兩個方法,一個是能把明文(整數)轉成未定性密文(整數) 的保密系統,另一個是能把明文(s維向量)轉成未定性密文(t維向量)的保 密系統,他們的未定性主要因為我們使用了未定性數字表示法(NNR),並 與LCL合併,而提出了新的保密系統。這個保密系統有一個重要特性"一對 多",這是從未定性數字表示法(NNR)得來的一個重要特性,所以要破其密 文;猜其明文,變得更加困難。也更增強其安全度。 In this paper, we study combination of LCL and NNR.We propose two new cryptosystem that one can transform one plaintext( integer) to different ciphertexts(integer) nondeterministicly at different times and other one can tranform one plaintext(s-tuple vector) to different ciphertexts(t-tuple vector) nondeterministicly at different times. The properties of nondetermination come from the usage of nondeterministic number representation (NNR) system. Combined with a LCL system, we propose two new cryptoscheme."One to many" is most important property of nondetermination, makes the guess of plaintext more difficult, hence enforces the security.zh_TW
