Abstract

A method for generating a seed value for use in symmetric encryption includes creating and storing a first data set and generating a hashed value based on the first data set. A replacement position in the first data set is selected, and at least a portion of the hashed value is written into the first data set at the replacement position. A seed portion of the first data set is selected as the seed value. By varying a number of iterations, a balance can be struck between performance (fewer iterations) and security (more iterations).
