Reformat Named Data Networking with Cryptographic Message Syntax

Abstract

The CCNx reference implementation uses XML and ccnb to describe and encode the Interest and Data packet, but currently most security communication uses CMS based on ASN.1 and BER to characterize the protocol packet. Therefore, in order to be compatible with these existing crypto technology and products, we propose to reformat the Interest and Data packet with CMS. In addition, BER encoding causes almost no increase in packet size compared to ccnb encoding, but it used less time spent on functions related to packet name decoding than XML-decoded.
