Hash function based on chaotic tent maps

In cryptographic applications, hash functions are used within digital signature schemes to provide data integrity (e.g., to detect modification of an original message). In this brief, we propose a new 2ℓ -bit iterated hash function based on chaotic tent maps. This hash function can be expected to have at least the same computational security against target attack, free-start target attack, collision attack, semi-free-start collision attack, and free-start collision attack as DM scheme.
