Grover hash
WebAs for Grover's algorithm, it provides quadratic advantage over classical computers for "black-box" queries. So a quantum computer could perform a brute-force attack in O ( N) trials whereas a classical computer would need O ( N) trials.

WebThe main result is Grover's search algorithm: a method for a quantum computer to search in an unsorted database of size $N$ with time $O (\sqrt {N})$ (while classically it will take an expected time of $N/2$). With Grover's algorithm, finding a preimage of a hash function whose output is $k$-bits takes $O (2^ {k/2})$ time, rather than $O (2^k)$.
