Abstract
A probabilistic system and method facilitates the sharing of a secret among participating users in a private way. The secret shares satisfy the condition that their sum equal a predefined number that is chosen by a third party aggregator. Without interacting with any other user, each user computes a secret share according to a predefined probability density function. If enough parties join, their secret shares can be combined by the aggregator with relative efficiency into a secret with a high likelihood of success.
