  • Using Signed Tokens to Verify Short Message Service (SMS) Message Bodies
    Publication number: 20240031156
    Abstract: Aspects of the disclosure relate to message verification. A computing platform may generate a cryptographic key pair comprising a public key and a private key. The computing platform may publish, to a server, the public key. The computing platform may generate a short message service (SMS) message. The computing platform may sign, using the private key, the SMS message, which may include computing a cryptographic hash of the SMS message using the private key and embedding the cryptographic hash in an SMPP field of the SMS message. The computing platform may send, to a downstream computing system, the signed SMS message, where the downstream computing system may be configured to validate the signed SMS message using the cryptographic hash embedded in the SMPP field of the SMS message and by accessing the public key.
