Anonymous private shared partitions in a global total order broadcast domain networks using random symmetric encryption keys

An operator for a global total order broadcast domain may send an operation out of band to nodes of participating parties, receive a certificate and a signature on an operation identifier for each participating node, generate a randomness vectors for each party participating in the operation, genera...

Zusammenfassung:An operator for a global total order broadcast domain may send an operation out of band to nodes of participating parties, receive a certificate and a signature on an operation identifier for each participating node, generate a randomness vectors for each party participating in the operation, generate a random symmetric encryption key, encrypt the certificates, the signatures, and the randomness vector for each participating party with the symmetric encryption key, encrypt the symmetric encryption key under each public key for each participating party, and hash the symmetric encryption key, and recording, by the operator, the hashed symmetric encryption key on the global total order broadcast domain.
