From Wireless Sensor Networks to Wireless Body Area Networks: Formal Modeling and Verification on Security Using PAT

Algorithm 9

Intruder() =

  //sends to CU messages by pretending to be a legitimate sensor node

  ca!ID.(No.RandLoc()).CU_1 -> Intruder()

  ca!ID.(No.RandLoc()).CU_2 -> Intruder()

  //intercept messages from the channel

  ca?ID_.Loc_.ID_ -> Intruder()

  cb?ID_.Loc_.ID_ -> Intruder()
