WebTypes of security of hash functions [ edit] Generally, the basic security of cryptographic hash functions can be seen from different angles: pre-image resistance, second pre-image resistance, collision resistance, and pseudo-randomness. Pre-image resistance: given a hash. h {\displaystyle h} it should be hard to find any message. Weba lightweight cryptographic hash function. It takes a 256bit - message block and a 256bit chaining variable as inputs and - produces a 256bit output. Its weight is 8.1 kg. Bogdanov et al. - [8] developed Spongent lightweight hash functions based on the sponge construction instantiated with permutations [9].
