Named data Networking (NDN) had been considered as a most recognizable Information Centric Networking (ICN) infrastructure. The deployment of NDN in the internet architecture requires the confidentiality and integrity of the contents. In this context, Elliptic Curve Digital Signature Algorithm (ECDSA) is a more promising algorithm. This research applied Montgomery Reduction on the existing asymmetrical security algorithm to shorter the processing period, lower the memory consumption and reduce the complexity over large computational requests. An experiment had been implemented in NDNv2 over ndnSIM environment. The results showed that modified ECDSA has reduced the processing period of 1% - 3% in private key generation and 50% in public key signing based on exponential analysis on modified ECDSA over existing ECDSA in key generation. The total time required to establish the connection among the nodes in NDN also has reduced of 12% by using modified ECDSA over ndnSIM.
