A Novel Secure Access Method for Remote Databases Based on Mobile Agents

With the rapid development of network, some novel applications like remote database access, electric commerce, etc. bring forth many new requirements for network loads, network communication efficiency and network security. This paper adopts mobile agent technology to achieve remote access to databases. Compared to the traditional C/S computing model, this method can significantly improve the communication efficiency and system performance when a large number of data located at remote sites must be handled. In addition, the security of data can be enhanced to some extent by using message digest, encryption and decryption techniques on the results carried by mobile agents. The experimental result shows that this access method for remote databases based on mobile agents is security and feasible. Especially to a large number of remote data processing, this technology gets more advantages over the C/S computing model in the aspect of performance.
