SECURE ROAMING SERVICES FOR INTERNET OF THINGS ARCHITECTURE

Abstract

Internet of things (IoT) is an emerging future networking paradigm. In IoT Communication between
heterogeneous networks is very attractive. However ensuring secure roaming service among heterogeneous
networks is challenging, since each network will have its own security policies that is different from one another
it becomes difficult to fulfil the security requirements from heterogeneous networks and since the processing
power of most wireless devices could be limited, hence in such a resource constrained environment there is a need
for an encryption technique that should support the low processing speed and limited memory space. The proposed
system focuses on providing a universal secure roaming architecture and multi-level privacy preservation.
Security is achieved by encryption of data using elliptic curve cryptography which is lightweight, scalable and
secure. A conditional privacy-preserving authentication with access linkability aims to provide privacy
preservation.
