Performance analysis of enhanced secure socket layer protocol

Abstract

The field of Network Security and the subfield of cryptographic protocols are both vast and continually evolving and expanding fields. The use of cryptographic protocols as a means to provide security to web servers and services at the transport layer, by providing both encryption and authentication to data transfer, has become increasingly popular. Secure socket layer (SSL) protocol establish secure session between client and server after authenticating both of them. The critical factor which decides the performance of the server is the SSL connection. When no. of SSL connection on the server is raised, the throughput will be decreased. According to the standard SSL protocol, an enhanced model of SSL combines Diffie-Hellman algorithm is implemented and its performance are measured on network simulator by considering various parameters like Packet Delivery Ratio (PDR), Throughput, Delay and Node Energy. The performance of SSL combines Diffie-Hellman algorithm is compared with the existing SSL protocol, Adhoc ondemand distance vector (AODV) under Denial of service (DOS) attack. SSL combines Diffie-Hellman algorithm will reduce the delay, node energy and enhance the PDR of the server so that it can handle more no. of client and server when no. of SSL connection is raised. SSL is one of the most common protocols used for secure communication over the internet. Users have grown to trust SSL and are prone to overlook visual clues that could indicate a security breach. But SSL is vulnerable to man in the middle attacks also.
