High density information encryption and transmission algorithm for large scale database

Abstract

The current high density information encryption transmission algorithm for large scale database has unsatisfactory encryption and decryption effects and low transmission security performance. This paper propose a high density information encryption transmission algorithm for large scale database. First, three DES is utilized to encrypt high density information of large scale database. Then, the communication protocol is constructed, mainly includes two parts. The initial authentication transmission protocol completes the basic authentication and information transmission function. The following authentication transmission protocol simplifies the communication process and implements fast identity authentication and information transmission function. Experimental results show that the authentication and information encryption process in this algorithm are encrypted with three DES, which can effectively protect the confidentiality and integrity of information, and achieve secure transmission.
