基于ECDH与Rijndael的数据库加密系统
Database Encryption System Based on ECDH and Rijndael
摘要
Abstract
Aiming at the issue of high risk of Database(DB) plaintext leakage,a DB encryption scheme based or Elliptic Curve Diffie-Hellman(ECDH) and Rijndael is proposed in this paper,which supports three kinds of key length,including 128 bit,192 bit and 256 bit.The session key is generated by the private key and public key.The private key is independent of the Database Management System(DBMS),which can eliminate the possibility of key leakage from the database.An experiment is performed on the.Net platform.Experimental results show that the new scheme can resist exhaustive attack,differential attack,etc.,and the maximum key space is 2256,and the encryption time,encryption efficiency and key sensitivity is desirable.关键词
