In cryptography, SWIFFT is a collection of provably secure hash functions. It is based on the concept of the fast Fourier transform (FFT). SWIFFT is not the first hash function based on the FFT, but it sets itself apart by providing a mathematical proof of its security. It also uses the LLL basis reduction algorithm.
Abstract. We propose a family of fast and provably secure crypto- graphic hash functions. The security of these functions relies directly.

What is provably secure hash functions?
Provably secure hash functions. In this approach, the security of a hash function is based on some hard mathematical problem, and it is proved that finding collisions of the hash function is as hard as breaking the underlying problem.
What is the most secure cryptographic hash function?

What is the fastest secure hash algorithm?
xxHash is an Extremely fast Hash algorithm, running at RAM speed limits. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions.
Is SHA-256 provably secure?
Seems the compression f in SHA256 is not provably secure, just hard. It's worth noting that RSA and ECDSA are currently also not provably secure. We believe factoring and DLP are hard because no one we know of has found a way to do it efficiently. But we have no proof of their hardness, and perhaps we never will.
