Improved Densification of One Permutation Hashing [PDF]

open access: yes, 2014
The existing work on densification of one permutation hashing reduces the query processing cost of the $(K,L)$-parameterized Locality Sensitive Hashing (LSH) algorithm with minwise hashing, from $O(dKL)$ to merely $O(d + KL)$, where $d$ is the number of ...

Construction of universal one-way hash functions: Tree hashing revisited

open access: yesDiscrete Applied Mathematics, 2007
AbstractWe present a binary tree based parallel algorithm for extending the domain of a universal one-way hash function (UOWHF). For t⩾2, our algorithm extends the domain from the set of all n-bit strings to the set of all ((2t-1)(n-m)+m)-bit strings, where m is the length of the message digest. The associated increase in key length is 2m bits for t=2;
