Key Establishment in Wireless Sensor Networks
Ioannis Chatzigiannakis, Elisavet Konstantinou · Wireless networks and mobile communications · 2009
In this book chapter we will consider key establishment protocols for wireless sensor net- works. Essentially, once two (or more) entities have authenticated each other, they usually can establish a key, in order to secure their future communications; conversely, an already established key can be very useful to perform future authentication.
