| + | abstract = {In this paper, we present free-start collisions for the TIB3 hash functions with a complexity of about $2^{32}$ compression function evaluations. By using message modification techniques the complexity can be further reduced to $2^{24}$. Furthermore, we show how to construct collisions for TIB3 slightly faster than brute force search using the fact that we can construct several (different) free-start collisions for the compression function. The complexity to construct collisions is about $2^{122.5}$ for TIB3-256 and $2^{242}$ for TIB3-512 with memory requirements of $2^{53}$ and $2^{100}$ respectively. The attack shows that compression function attacks have been underestimated in the design of TIB3. Although the practicality of the proposed attacks might be debatable, they nevertheless exhibit non-random properties that are not present in the SHA-2 family.} | ||
