Website information retrieval of web database based on symmetric encryption algorithm

Abstract

With the diversification of information development, data security is becoming more and more important. Therefore, the research on website information retrieval of Web database based on symmetric encryption algorithm is studied. From the security performance of Website information retrieval of Web database, the improved chaotic map encryption algorithm is used to enhance the hyper chaos of the key. It is undeniable that digital signature can improve the security of Web database information authentication. Based on this; the Web information retrieval method based on mobile Agent is adopted. This method is a modular structure of multi-agents that is divided and cooperated by five types of Agents. Through the division and cooperation of the user interaction Agent, retrieval management Agent, evaluation screening Agent, preference acquisition Agent, and the network spider Agent, the user’s preference is selected. Finally, the effective retrieval of Web information is achieved. The experimental results show that this kind of retrieval method can comprehensively and effectively retrieve the information of various commodities in website of the logistics company, and the retrieval performance is better.
