Data security enhancement using secure hash function

Abstract From the Canadian patent

Apparatus and methods for data security enhancement involving receiving a master key and generating a derivative key from the master key using an implementation of a universal hash algorithm and a secure hash algorithm. Key derivation may be done by securely hashing a master key using a processor to produce a hash value determining a first number and a second number from the master key computing a universal hash function of the hash value the first number, and the second number to produce a result and selecting a derivative key from bits in the result. Key derivation may also be done by dividing the master key into a first segment and a second segment securely hashing the first segment …
