Abstract
A method for message management is disclosed. The method includes: deriving, by a first subscriber node (SN), a secret value associated with a publisher node (PN); generating, by the first SN, a first expected sequence number using a one-way function and the secret value; receiving, by the first SN, a first publisher message generated by the PN and including a first sequence number; validating, by the first SN, the first publisher message by comparing the first sequence number with the first expected sequence number; processing, by the first SN, a payload of the first publisher message in response to the first sequence number and the first expected sequence number matching; and generating, by the first SN node, a second expected sequence number using the one-way function, the first sequence number, and the secret value.
