Design and Implementation of Hop to Hop Message Authentication and Source Privacy in Wireless Sensor Networks

Message authentication is one of the most effective ways to thwart unauthorized and corrupted messages from being forwarded in Wireless Sensor Networks (WSNs). For this reason, many message authentication schemes have been developed, based on either symmetric-key cryptosystems or public-key cryptosystems.
