A mutual key agreement protocol to mitigate replaying attack in eXpressive internet architecture (XIA)

Several Future Internet (FI) architectures have been proposed to address the problems of the Internet including flexibility (so called IP bottleneck), host-based addressing (addressing a host rather than the content itself), and security. In this paper, we focus on eXpressive Internet Architecture (XIA) as it is the most secure and open-source Content-Centric Network (CCN). CCN is claimed by the Future Content Networks (FCN) Group to be the Future Internet (FI). However, XIA does not have any mechanisms to mitigate the replaying attack, thus, this paper proposes and implements a solution to mitigate it. Several existing solutions have been analyzed to derive the requirements for the proposed solution. By implementing the proposed protocol, XIA is now able to mitigate all of the reviewed network attacks. The evaluation shows that the proposed solution is more secure and less complex over the existing solutions
