seCurity and PrivaCy in smart Grids
by encrypting blocks of the plaintext at a time. e computational
overhead of RC4 (stream cipher), IDEA and RC5 (block ciphers), and
MD5 and SHA1 (one-way hash functions) have been evaluated in
the work of Ganesan et al.

Different sensor platforms were used for
testing these algorithms. It was shown that RC4 outperformed RC5
across all platforms. e hashing algorithms have an order of mag-
nitude higher overhead compared to the symmetric key algorithms.
Several block ciphers were evaluated for their applicability in sen-
sor networks in the work of Law et al.

e storage requirements and
energy efficiency of the ciphers were also considered along with their
security properties. e authors proposed Rjindel ...
