PS3 (Asymmetric – ECDSA)

other linux function on PS

“when fail0verflow worked backwards from generated keys, they found out that a parameter that should have been randomized for each key generation wasn’t being randomized at all. Instead, the PS3 was using the same number for that variable, every single time, making it easy to work out acceptable keys.”

“In December 2010, a group calling itself fail0verflow announced recovery of the ECDSA private key used by Sony to sign software for the PlayStation 3 game console. However, this attack only worked because Sony did not properly implement the algorithm, because {\displaystyle k}k was static instead of random. As pointed out in the Signature generation algorithm section above, this makes {\displaystyle d_{A}}d_{A} solvable and the entire algorithm useless.[6]
