Practical Related-Key Forgery Attacks on the Full TinyJAMBU-192/256
Abstract
TinyJambu is one of the finalists in the NIST lightweight cryptography competition. It has undergone extensive analysis in the recent years as both the keyed permutation as well as the mode are new designs. In this paper we present a related-key forgery attackon the updated TinyJambu scheme with 256- and 192-bit keys. We introduce a high probability related-key differential attack were the differences are only introduced into the key state. Therefore, the characteristic is applicable to the TinyJambu mode and can be used to mount a forgery attack. The time and data complexity of the forgery are
