摘要
There is provided a method of generating a key for encrypting Communications between first and second terminals comprising obtaining a measurement of characteristics of a physical identifier of a user; and extracting a key from the physical identifier using a code selected from a collection of codes, each code in the collection defining an ordered mapping from a set of values of the characteristics to a set of keys; wherein the collection of codes comprises at least one code in which the ordered mapping is a permutation of the ordered mapping of one of the other codes in the collection.
