Cryptography FMEpisode 10: Exploiting Authenticated Encryption Key Commitment!Authenticated encryption such as AES-GCM or ChaCha20-Poly1305 is used in a wide variety of applications, including potentially in settings for which it was not originally designed. A question given relatively little attention is whether an authenticated encryption scheme guarantees “key commitment”: the notion that ciphertext should decrypt to a valid plaintext only under the key that was used to generate the ciphertext.
In reality, however, protocols and applications do rely on key commitment. A new paper by engineers at Google, the University of Haifa and Amazon demonstrates three recent applications where missing key commitment is exploitable in p...2020-12-0146 min

RaumZeitLabor PodcastArcade Games: Hacking, Emulation, Preservation (Ange Albertini)The awesome Ange Albertini gave another great talk at RaumZeitLabor.
This time it's all about Arcade Games.
The talk focusses on hacking the CPS2 arcade game system by capcom and how it was eventually hacked to make games emulatable and thus preserve them from death by the suicide battery that was included on the games PCB.2014-12-121h 20
