Abstract

A method for distributing a shared secret key among a plurality of nodes is described. Each node establishes a secret key, the number of nodes being more than two nodes. A node distributes by a ring protocol executing over computer network connections an encrypted version of the secret key of each node to other nodes of the plurality of nodes. Each node decrypts the secret keys of other nodes so that each node has the secret key of other nodes. Each node combines the secret keys of other nodes to form a shared secret key available to other nodes.
