Internet of Things From Hype to Reality

The Internet of Things (IoT) has gained significant mindshare, let alone attention, in academia and the industry especially over the past few years. The reasons behind this interest are the potential capabilities that IoT promises to offer. On the personal level, it paints a picture of a future world where all the things in our ambient environment are connected to the Internet and seamlessly communicate with each other to operate intelligently. The ultimate goal is to enable objects around us to efficiently sense our surroundings, inexpensively communicate, and ultimately create a better environment for us: one where everyday objects act based on what we need and like without explicit instructions

Redesigning of IPSec for interworking with satellite performance enhancing proxies

Performance Enhancing Proxies (PEPs) are used in satellite networks for better performance of the TCP/IP applications. Multi-layer IPSec (ML-IPSec) resolves the conflict between end-to-end security in standard IPSec and working of PEPs. This paper presents the concept and detailed design of ML-IPSec by breaking the IP datagram into three zones while enabling the intermediate nodes to access the TCP header and HTTP header information. The paper also presents an efficient interworking scheme between ML-IPSec and secure IP multicast using the Logical Key Hierarchy for key distribution. © 2011 IEEE
