Example text

They formulate as an interesting open problem to determine whether the security improves with the length of the cascade also for lengths l > 3. However, the proof in [4] contains a few bugs, which we describe in the appendix of this paper. The first part of our contribution is to fix these errors and to reestablish the lower bound on the security of triple encryption up to a constant factor. Second, we have rephrased the proof into the random systems framework introduced in [10]. Our goal here is to simplify the proof and express it on the most abstract level possible, thus making the main line of reasoning easy to follow and clearly separated from the two technical arguments required.

The Key-Dependent Attack on Block Ciphers 23 The time complexity of the key-dependent attack is determined by the time complexity of each individual attack and the order of performing these individual attacks. For a key-dependent subset (P, U ), the time needed for individual attacks relies on the entropy of P : the closer P is to the random distribution, the more difficult the attack is—to ensure the same probability of making the right judgement, the attack needs more encryptions. This indicates that individual attacks for different key-dependent subsets have different time complexities.

2. The key-dependent distribution of P rob(LSB(∆s) = 1) on the value of Z5i If (pi ∗ Z5i ) + (8000x ∗ Z5i ) is smaller than 216 + 1, then LSB(s i ) = LSB(si ) ⊕ LSB(8000x ∗ Z5i ) holds because of the equivalence of XOR and modular addition for the least significant bit. Moreover, LSB(∆si ) = LSB(8000x ∗ Z5i ) is satisfied, which means LSB(∆si ) = LSB(8000x Z5i ) Otherwise, LSB(s i ) is equal to LSB(si ) ⊕ LSB(8000x ∗ Z5i ) ⊕ 1 because of the carry. So LSB(∆si ) equals to LSB(8000x Z5i ) ⊕ 1. Therefore, we may conclude that LSB(∆si ) = LSB(8000x Z5i ) if and only if the pair (pi , p i ) satisfies (w ∗ Z5i ) + (8000x ∗ Z5i ) < 216 + 1, where w is either pi or p i , whichever between 1 and 8000x.
