seCurity and PrivaCy in smart Grids
used. e two communicating partners are assumed to know the val-
ues of the counters, and the counters do not need to be added to each
ciphertext. Messages may become lost, and the two counters need to
be synchronized occasionally (e.g., at off-peak time). A simple counter
synchronization protocol is proposed for the sSCADA protocol suite.
e counter synchronization protocol could also be initiated when some
encryption/ decryption errors appear due to unsynchronized counters.
For two sSCADA devices to establish a secure channel, a master
secret key needs to be bootstrapped into the two devices at deployment ...
