dc.description.abstract在本文中,我們實作一個D-N密碼系統應用於資料庫上,此系統能產生金匙及將資料庫中的關係編碼成為密文,並將金匙儲存成檔案,以成為解碼時重要的依據。由於NNR的不確定性使得產生出來的密文讓人難以破解。一個密碼系統由明文(M)、密文(C)、編碼系統(Encryption)、解碼系統(Decryption)與金匙(key)五個部分所組成[7]。我們使用的是對稱式(symmetric)編碼系統,也就是祕密金匙(secret-key)系統。最後,我們將分析此密碼系統的效能zh_TW
dc.description.abstractIn the paper, we implemente an D-N Cryptosystem apllied on database. By the cryptosystem, we can generate the key and encrypt the relation to ciphertext and store the key in the file for decryption.. This vector works on the vectors domain, that is, both input and output are vectors. The property of nondetermination makes the guess of plaintext more difficult to ensure the security.en_US
