Abstract

See full text

A method for storing and retrieving a key using a hash table, the method comprising the steps of: (a) hashing the key using a first hash function, thereby transforming the key into a table address in the hash table; (b) hashing the key using a second hash function, distinct from the first hash function, thereby transforming the key into a key signature; and (c) entering the key signature in a signature page located at the table address.
