Type of Analysis	Hash Function Part	Hash Size (n)	Parameters/Variants	Compression Function Calls	Memory Requirements	Reference
pseudo-collision	compression	all		-	-	Bagheri
pseudo-2nd preimage	compression	all		-	-	Bagheri
preimage(1)	hash	512		2510.3 (+ 2524 MA + 2524 CMP)	2510.3 (Wu: 2510.6)	Mendel,Thomsen, Wu

A description of this table is given here.

⁽¹⁾ Wu has analyzed the exact memory requirements, additional memory accesses (MA) and comparisons (CMP) of the attack by Mendel and Thomsen.
