This document proposes an integrated, secured, and intelligent architecture for connecting the Internet of Things (IoT) and cloud computing. The key components of the proposed architecture are: (1) an intelligent system using intelligent smart cards and readers, (2) an IP/MPLS core, (3) an integrated cloud IoT platform, and (4) a security gateway using elliptic curve cryptography. Experimental results show the system can authenticate users and devices securely while providing reasonable response times under increased loads. The proposed architecture aims to provide a novel way to access applications securely from IoT devices using a single smart card.
