Could you elaborate on your claim that there's flaws in Motorola's AES encryption?
- rwaksmunski 2y agoTheir implementation added one more round of encryption for unknown reasons, which turns out weakened AES enough to break it with a GPU cluster. Google looks to be well scrubbed of the story but it featured on HN a while back.
- rsynnott 2y agoI'd assuming they're talking about TETRA, presumably one of the export versions (I don't think TEA2 (only available to European public safety orgs) is known to be broken at this point, though its age and obscure nature wouldn't give you much confidence). There's a good talk on it here: https://media.ccc.de/v/37c3-11761-all_cops_are_broadcasting https://media.ccc.de/v/37c3-11761-all_cops_are_broadcasting
