Cost-Performance Optimization of SSL-Based Secure Distributed Infrastructures
Business-to-Business and Business-to-Customer transactions in Internet require secure communication, especially for web applications. The Secure Socket Layer (SSL) protocol is one of the most viable solutions to provide the required level of confidentiality, message integrity and endpoint authentication. The two main alternatives for providing SSL security are the end-to-end and the accelerated solutions, which enable different cost-performance tradeoffs, where performance is intended as the overall delay that the customer experiences to complete the transaction. The accelerated solution is enabled by special devices (SSL acceleration cards) placed in network nodes.
