N. Thenmozhi, M. Madheswaran . Dynamically Changing the Symmetric Encryption Algorithm for Improving Security and Performance during Data Transfer in Grid Networks. International Journal of Computer Applications. 55, 7 ( October 2012), 22-27. DOI=10.5120/8766-2687
Abstract
In grid design authentication, authorization and confidentiality of the communication between computers are important security requirements. Without the functionality, the integrity and confidentiality of the data processed, the grid would be at risk. There are many different tools and technologies, which are available to ensure secured grid environment. The symmetric and asymmetric encryption algorithms are commonly used algorithms in grid software to provide necessary security, even though symmetric encryption algorithm significantly will affect the network communication performance. The previous work relied on the use of encryption and decryption at the application layer has an impact on the application layer performance and in the network layer performance. In the proposed work, instead of using a single encryption algorithm different encryption algorithms were selected arbitrarily during processing of each packet. The performance has been measured through simulation studies on NS2 by simulating these algorithms on GARUDA Grid Network Topology.
