However, for the case of invertible primitives, there is a glitch. In this errata, we formally fix this glitch by adding an extra term to the security bound, <em>q</em>/2<sup><em>b</em>−<em>n</em></sup>, where <em>q</em> is query complexity, <em>b</em> the width of the permutation or the block size of the block cipher, and <em>n</em> the size of the hash digest. For permutations that are wider than two times the chaining value this term is negligible. For block cipher based hashing modes where the block size is close to the digest size, the term degrades the security significantly.</p>}, number={3}, journal={IACR Transactions on Symmetric Cryptology}, author={Gunsing, Aldo and Daemen, Joan and Mennink, Bart}, year={2020}, month={Sep.}, pages={362–366} }
