Analysing and Improving Performance and Security of Cryptographically Generated Address Algorithm for Mobile IPv6 Networks

A Cryptographically Generated Address (CGA) is a selfcertifying address that a node generates when it joins a foreign network. Despite its advantages, generating a CGA is computationally expensive. This study examines the security and performance issues related to the use of the CGA Generation algorithm. It also scrutinizes the hash extension mechanism, different hash functions and how multithreading can be used to improve the performance of the CGA Generation algorithm. Based on the results, this research recommends imposing a minimal computational security of O(2), the use of the HAVAL hash function and parallelizing the algorithm in order to take maximum advantage of multicore architectures of mobile node.
