damaged or disabled nodes may still have the initial key in
the flash memory. Therefore, should an adversary physically
capture such a node and obtain the initial key, all the pairwise

sensor node can derive a separate encryption key and a MAC
key from the individual key [21]. This method can also
be applied to enhance security in data tran...
