Dumb Crypto in Smart Grids: Practical Cryptanalysis of the Open Smart Grid Protocol
Philipp Jovanovic and Samuel Neves
Abstract
This paper analyses the cryptography used in the Open Smart Grid Protocol
(OSGP). The authenticated encryption (AE) scheme deployed by OSGP is a
non-standard composition of RC4 and a home-brewed MAC, the ``OMA digest''.
We present several practical key-recovery attacks against the OMA digest. The
first and basic variant can achieve this with a mere
