Research and Implementation of Relational Database Encryption Technology Based on Main Memory Database

As the relational database is applied widely, how to protect the sensitive data and state secrets has become a problem which needs to be solved urgently. The conventional relational database encryption technology not only reduces the system’s performance, but also results that we can not quickly inquire the encryption data through the original index mechanism due to the loss of the original partial order relation among data. This paper proposes a kind of relational database encryption technology based on the main memory database. It has not only realized the transparent encryption, decryption and ciphertext storage of the relational database, but also still retained the original response and retrieval performance. This technical proposal has very strong adaptability as well as strong practice guidance meaning for protecting the internet business data and the war-industry informative state secrets.
