MANAGING SMS SPOOFING USING SMPP PROTOCOL

Systems and methods are disclosed for managing Short Messaging Service (SMS) spoofing using Short Messaging Peer-to-Peer (SMPP) protocol. An SMPP protocol communication includes an SMPP transmitter and an SMPP transceiver. The SMPP transmitter identifies or receives an SMS message for transmission to a destination. The SMPP transmitter identifies a source address for the SMS message, and determines whether the source address is authentic. If the source address is not authentic, then the SMPP transmitter inserts a validity indicator in an SMPP Packet Data Unit (PDU), along with the SMS message, that the source address is not authentic before transmitting the SMPP PDU to the SMPP transceiver. Upon receiving the SMPP PDU from the SMPP transmitter, the SMPP transceiver may determine whether or not to deliver the SMS message to the destination based on the validity indicator provided by the SMPP transmitter.
