Research of database encryption based on fast AES algorithm implementation

Abstract

At present, there are many research achievements in the field of block cipher. Especially, the AES (Advanced Encryption Standard) algorithm should be considered the excellent representative of all the researches. When the data encryption standard was replaced by the advanced encryption standard, the whole world was putting light on the AES algorithm. Some research showed that the AES algorithm can be implemented fastly by shifting, xor and looking up tables. In this paper, we studied the implement of the fast AES algorithm in database system because database encryption technology was paid more attention. Through testing, we can see that the use of fast AES algorithm on the database system has little effect upon the efficiency of the database. © 2011 Springer-Verlag Berlin Heidelberg.
