The program they created is called Singstar Ripper found here /manpages/trusty/man1/ss_extract.1.html. There is conflicting information about whether they broke encryption on both PS2 and PS3 disks. This means that they broke the encryption. They apparently had success and created a program to convert Singstar disks to Performous files. Known plain text attacks have been successful but they don't get us very far because different SingStar releases use different keys."ģ. "These seem to be encrypted in AES128-CTR mode but we haven't been able to extract the keys. This means that the algorithm is sufficiently weak to allow for known plain text attacks but so far we haven't been able to figure out exactly what kind of substitution is used or to extract the key."Ģ. The substitution table depends on byte offset but no other factors. pkf file with substitution cipher applied. "Concerning the PKD, we found out that the encryption is vulnerable to watermark attack and thus were able to identify that it is actually a. I have found information from the Performous project in which they found the following information about the Singstar disks.ġ.
