IPSec: Performance Analysis in IPv4 and IPv6

Internet Protocol security (IPSec) is an end-to-end security scheme to provide security at the IP network layer, but this comes with performance implications leading to throughput reduction and resource consumption. In this paper we present a throughput performance analysis of IPSec protocol, for both IPv4 and IPv6, using various cryptographic algorithms as recommended in the standards [13]. In this study we have considered only throughput performance for authenticated encryption algorithms AES-GCM and AES-CCM, encryption algorithms AES-CBC, AES-CTR, and 3DES, and authentication algorithms SHA1, SHA2 and XCBC. The result shows that AES-GCM provides better performance compared to the other recommended algorithms.
