... tamper-proof hardware, 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 keys ... each 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...
