Comparison of ECDSA and RSA signature scheme on NLSR performance

The Named-data Link State Routing protocol (NLSR) is an intra-domain routing protocol for Named Data Networking (NDN). It is an application level protocol similar with many IP routing protocols, but NLSR uses NDN's Interest/Data packets to disseminate the routing updates, directly benefit from NDN's built-in data authenticity. The security mechanism has been directly embedded inside the NDN protocol, thus a digital signature scheme is needed to check the integrity of each NLSR packets that exchanged between node that run NLSR. By default, NLSR uses RSA and ECDSA as digital signature algorithms that are proven to be efficient against attacks, but both have their respective advantages and disadvantages due to differences in computation and key methods used. The main purpose of our research was to find the optimal algorithm that give the best synchronization time during the signature scheme. Our experiment result show that RSA scheme performance speed is better than ECDSA scheme on NLSR in sync speed with 0.062558226% difference.
