Web4 mei 2024 · In this paper, we apply meet-in-the-middle attack to QARMA-64 and QARMA-128 including the outer whitening keys. First, we observe that a linear relation exists between four cells out of the eight input/output cells in the MixColumns operation. WebA meet-in-the-middle attack involves a time-space trade-off to drastically reduce the effort to perform a brute-force attack. For example, if one can devise a mechanism to reduce an operation with a 64-bit key that would need 2^64 brute-force operations to 2^32 operations, a brute-force attack becomes feasible.

We end this section with explaining how a low-memory search for collisions works as was described in [25]. In Section 3 we describe how we can use this collision search in the meet-in-the-middle attack to achieve the reduction in the required memory.
