Osmo-GMR now supports A5-GMR-1 cipher

Added by tnt over 5 years ago

Osmo-GMR now has support for cipher stream generation. This allows to see past the CIPHER MODE COMMAND in the examples (I will put the key along with the demo files soon).

You can see the actual code in the git : ​

The algorithm was re-implemented by the Osmo-GMR team based on the reversing work done at the University of Bochum by a team comprised of Benedikt Driessen, Ralf Hund, Carsten Willems, Christof Paar, and Thorsten Holz. The Osmo-GMR team actually contributed in the late stages of this work by providing real world captures to validate the reversed algorithm and the attacks.
