Abstract-Due to overheads of security algorithms used in IPSec, transferring data using IPSec is known to be significantly slow compared with open system. In this paper, we present new results on performance of IPSec using 7 encryption systems for both IPv4 and IPv6 using Windows 7 and wireless network access. For the system studied, enabling IPSec results in approximately 60% (IPv4) and 48% (IPv6) less TCP throughput compared to open system. Among encryption mechanisms, 3DES-SHA provides the highest TCP bandwidth for IPv4, while 3DES-MD5 gives the best result for IPv6. We also provide the results for UDP.
Abstract-IPSec (IP Security) is a robust technique for securing communications over the Internet. Due to security algorithms used, transferring data using IPSec is known to be significantly slow. In this paper using a test bed environment for a site to site IPSec, we present new results on performance of IPSec for both IPv4 and IPv6 using Fedora 15 operating system and wireless network. Compared to open system, enabling IPSec results in approximately 50% and 40% less throughput for IPv4 and IPv6 networks respectively.
Abstract-IPSec (IP Security) and SSL (Secure Socket Layer) are the main technologies for securing communications via the Internet. In this paper, we present new results on the performance of SSL using Windows 7 operating system under IEEE802.11n wireless network. Enabling IPSec security results on average approximately 50% less TCP throughout while enabling SSL security results on average approximately 96% less TCP throughput compared to open system. In IPSec, 3DES-SHA encrypted system outperformed AES128-SHA encrypted system with a maximum difference of 2.40 Mbps for packet size of 1408. However, in SSL, AES128-SHA and 3DES-SHA had almost the same performance.
