The Open Smart Grid Protocol Alliance said updates will be rolled out in September to networks and devices that address weak homegrown cryptography pointed out in a research paper. The OSGP Alliance said it will then work with standards bodies such as CENELEC and ETSI in Europe to bring smart grids and devices up to speed. In a paper published April 27, researchers from Germany and Portugal exposed encryption weaknesses in the protocol in a paper entitled Dumb Crypto in Smart Grids: Practical Cryptanalysis . The primary issue is that the authenticated encryption scheme is homegrown.
