Me: "Universal Fault Attack on All Public Key Algorthms" Abstract. Fault the memcpy, serial interface, etc. pointer to copy out part of the secret key instead of ciphertext or signature at the end of the algorithm.

Now, where do I collect my Levchin prize for solving cryptanalysis ?

Everyone can go home now and forget about cryptography because it's all broken by this fault attack
But seriously, this one is technically more plausible than some fault attacks I've seen proposed. Who would have the kit to try it out on an actual target?2 replies 0 retweets 4 likesShow this thread
Replying to @mjos_crypto
It's been done before. It's hard to fault a specific address to another one though. Easier to fault the conditional jump that tests for end of copy, and have it merrily copy until the end of memory.
