A collection of challenges for the Lightweight Competition.
For every cipher we created challenges with a reduced number of rounds/steps/etc., you get 2^20 plaintext ciphertext byte pairs (+tag) and the goal is to recover the key. In the challenges we added the specification and the code that we used to generate the plaintext/ciphertexts.
If you cannot find the cipher you want to attack in the list, then most probably we did not have time to implement it yet. Depending on the reference implementation, the time it takes to add the (round reduced) cipher to the system ranges from non-negligible to 'a lot'.
The system uses a special system to keep track of who did what. See the what page for more information. If you encounter any problems with it, please let us know.
Have fun and if you have suggestions/idea's/bugs/etc. you know who to contact.
Note that the ciphertext outputted by the system is in binary format. You can download the plaintexts used here
