Abstract: Creating hash values based on bit values of an input vector. An apparatus includes a first and a second hash table, a first and second hash function generator adapted to configure a respective hash function for a creation of a first and second hash value based on the bit values of the input vector. The hash values are stored in the respective hash tables. An evaluation unit includes a comparison unit to compare a respective effectiveness of the first hash function and the second hash function, and an exchanging unit responsive to the comparison unit adapted to replace the first hash function by the second hash function.
