Abstract

A key updater for a first party operating on a network generates a mutually distilled key for communication between the first party and a second party. The key updater determines a set of verifying parties operating on the network needed to authenticate the mutually distilled key, wherein each verifying party of the set of verifying parties operates on the network. The key updater iteratively executes a key equivalency test for each verifying party in the set of verifying parties to determine a nonce sum until the key equivalency test has been executed for each of the verifying parties in the set of verifying parties or until it is determined that at least one node on the network has been compromised. The key updater generates a final key for communication between the first party and the second party based on the nonce sum and the mutually distilled key.
