Hash function book
Webcryptographic hash family is a set of functions {Hk: k∈ K}, for somefinite set K, such that each function in the family is of the form Hk: {0,1}∗→ {0,1}l. The value k that specifies a hash function Hk from a hash family is called a key, but in many applications the key is not kept secret (an exception is message authentication codes).

WebPurely additive hash functions such as CRC fail this stronger condition miserably. Clearly, a strong hash function should have a uniform distribution of hash values. Bret Mulvey proposes the use of a chi-squared test for uniformity, based on power of two hash table sizes ranging from 2 1 to 2 16. This test is considerably more sensitive than ...
