Welcome to the resource topic for 2024/1887

Title:
Differential MITM attacks on SLIM and LBCIoT

Authors: Peter Grochal, Martin Stanek

Abstract:

SLIM and LBCIoT are lightweight block ciphers proposed for IoT applications. We present differential meet-in-the-middle attacks on these ciphers and discuss several implementation variants and possible improvements of these attacks. Experimental validation also shows some results that may be of independent interest in the cryptanalysis of other ciphers. Namely, the problems with low-probability differentials and the questionable accuracy of standard complexity estimates of using filters.
