TL;DR: In this article, a database array driving and dynamic indexing technology based on a block chain is proposed, which is guaranteed that the database encryption key is not leaked before, during and after the database array is driven and safe driving of the data is completed.
Abstract: The invention discloses a database array driving and dynamic indexing technology based on a block chain. The database array driving and dynamic indexing technology comprises a database array driving part and a database array dynamic indexing part. Block chain technology, By means of the advantages of the decentralized distributed structure, non-tampering of data, a safe trust mechanism, a flexibleprogrammable characteristic and the like, safety protection of the database encryption key is achieved, it is guaranteed that the database encryption key is not leaked before, during and after a database array is driven, and safe driving of the data is completed. And meanwhile, a dynamic index technology is introduced, so that the data storage and query efficiency, softness and expandability aregreatly improved.

TL;DR: 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.
Abstract: 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.

01 Dec 2010TL;DR: To deal with database security of Management Information System (MIS), a database encryption solution is designed and implemented and a multilevel cipher solution of application system is implemented in SQL Server 2005.
Abstract: To deal with database security of Management Information System (MIS), a database encryption solution is designed and implemented Analyzing the relation of database openness and security in the traditional model of MIS, the paper constructs an improved security model of MIS Based on database encryption theory, a multilevel cipher solution of application system is implemented in SQL Server 2005 Several experiments are carried out to compare the time spending of data manipulation based on some encryption algorithms in database The result shows that the symmetric encryption increases the time cost about 1/3 while the asymmetric encryption increases much more The solution is effective if it is applied to sensible data
