ChainHash Definitions

chain variable

A chain variable is a variable taking value in the set of all bit strings of a specified length.

block

A block is a bit string of a specified length.

compression function

A compression function is a function from the product space of the domains of a specified set of chain variables and the Set of all blocks of some fixed length to the product space of the domains of the chain variables.

initial value

An initial value is a explicitly specified point in the product space of the domains of a set of chain variables.

padding algorithm

A padding algorithm is an algorithm which appends bits to a bit string giving a new bit string whose length has some desired propery.

chain hash function

A chain hash function is a function constructed from a compression function, padding algorithm and initial value in such a manner as to have the following properties:
