Research on Database Encryption of OA System

For the current database security issues of office automation system, A database encryption scheme is proposed in this paper, which according to authority, roles, and the different encryption granularity of the database, not only ensure data security, but also improve the efficiency of system management. In order to enhance the security of the database, using ECC (elliptic curve encryption algorithm) flexibly, fully ensure the store of sensitive data’s security. Through experiments and performance analysis, the method can ensure the security of the database effectively.
