A Closer Look at the S-box: Deeper Analysis of Round-Reduced ASCON-HASH
Abstract
ASCON, a lightweight permutation-based primitive, has been
selected as NIST’s lightweight cryptography standard. ASCON-HASH is one of the hash functions provided by the cipher suite ASCON. At ToSC 2021, the collision attack on 2-round ASCON-HASH with time complexity 2^{103} was proposed. Due to its small rate, it is always required to utilize at least 2 message blocks to mount a collision attack because each message block is only of size 64 bits. This significantly increases the difficulty of the analysis because one almost needs to analyze equivalently at least
