Secure socket layer (SSL) is the most popular protocol to secure Internet communications. Since SSL handshake requires a large amount of computational resource, batch RSA was proposed to speedup SSL session initialization. However, the batch method is impractical since it requires a multiple of certificates. In this paper, we overcome this problem without modifying SSL protocol. To select the optimal batching parameters in terms of performance of server and durable waiting time of the client, we model the connection request with M/D/1 queue. We validate the solutions of the analytical model through simulation.
