Abstract
A method for byzantine fault-tolerant replication of data on a plurality of n servers includes performing, by a primary node (PN), a prepare procedure that includes computing a prepare message including a unique identifier and multicasting the prepare message to the REPN. The method further includes performing, by the PN, a commit procedure that includes receiving, from each of a portion of the REPN, a prepare message reply signature part and aggregating each of the prepare message reply signature parts to generate a prepare message reply aggregated signature, checking the validity of the prepare message reply aggregated signature, and upon determining that the prepare message reply aggregated signature is valid, computing a commit message including the prepare message reply aggregated signature and multicasting the commit message to the REPN. The method further includes transmitting, to the client, the commit message reply aggregated signature.
