Application: Using signed tokens to verify short message service (SMS) message bodies (Patent ID: US20240031156A1)

The patent filed by Proofpoint Inc. relates to message verification using a computing platform that generates a cryptographic key pair, publishes the public key to a server, generates a short message service (SMS) message, and signs the SMS message using the private key by computing a cryptographic hash and embedding it in an SMPP field. The signed SMS message is then sent to a downstream computing system for validation using the cryptographic hash and public key, ensuring message integrity and authenticity.

The computing platform can also store the private key or upload it to a Communications Platform as a Service (CPaaS) platform, allowing for flexibility in signing the SMS message. In case of signature validation issues, the platform can generate an abuse reporting format (ARF) message with policies for handling invalid messages. Additionally, the downstream computing system validates the signed SMS message by accessing the public key from an internet Domain Name Service (DNS) server, ensuring secure message transmission. Overall, the patent outlines a comprehensive method for secure message verification and handling potential validation problems effectively.
