Secure split knowledge multi-party secret generation

Abstract

A method to calculate a Secret as a first function of entropy values received from each of the participants. The calculated Secret S is then split using a second function to create a discrete share for each participant, wherein each discreet share is a function of the corresponding entropy values. Each discrete share may be distributed by non-private communication to the participant corresponding to its supplied entropy first value. Optionally, the Secret may be burned after use, but can be recalculated by a subset of the original participants as a third function of their respective entropy value and discrete share. Since the discrete shares are not sufficient to recreate the Secret without knowledge of the corresponding entropy values, the discrete shares may be distributed openly without the need for privacy, and need not be held securely.
