| Predmety: | Primitive groups, group generated by the round functions, cryptography, AES, invariant partitions, key schedule |
| Popis: | The AES key scheduling algorithm selects the round keys which are xor-ed with the partially encrypted state in each iteration. In this work, we examine the group that arises from the AES-128 key scheduling operation. We show that the smallest group _AES containing and all translations of the message space is primitive. This implies that we cannot have a linear partition of the message space that is invariant under the action of _AES . B |
