Comments from Accomplished People in the Field on
Security for Wireless Sensor Networks using
Identity-Based Cryptography
Security for Wireless Sensor Networks using Identity-Based Cryptography provides a step-by-
step approach to everything you’ll need to know about wireless sensor network security.
The book also has information about many topics relevant to wireless sensor network
security planning, design, and implementation of Identity-Based Cryptography, which
is a superior security solution with better resistance against known attacks.

Getting the right balance of systems security is a hard enough task in traditional net-
working, let alone securing a wireless network composed of sensors with high resource
limitations that, nonetheless, can collaborate to perform complex tasks. This book
serves as an excellent starting point for practitioners in the industry and students in
academia to come up to speed with security issues in wireless sensor networks.

Adjunct Professor, Department of Computer Science, Illinois Institute of Technology
Strong identity mechanisms are a hard sell for today’s Net because people feel that
they know who they’re talking to. In the Internet of Things with its focus on unfeeling
machine-to-machine communications, we must replace “feeling secure” with actually
being secure.  Wireless sensors are  the eyes, ears, noses and cat-whiskers of the Internet
of Things. Yet these sensors are connected by a network that can be subverted by hostile
parties, risking that their output could be diverted or false information inserted.  Given
the vast number of sensors to be deployed, cryptographic identity systems may be the
only manageable approach to trusting our senses.
