lthash-rs

Description and scope of the project

This repository contains an implementation of LtHash, as defined by Bellare and Micciancio and later specified more concretely by researchers at Facebook.

Limitations

LtHash is vulnerable to multiset input collisions. A multiset is a set containing more than one instance of a particular element. In particular, it is trivial to produce a collision in lthash16 by adding the same input to the hash 2^16 times. One way to prevent this is to concatenate each input with a unique piece of metadata, such as an index.
