Using signed tokens to verify short message service (sms) message bodies

A method comprising:

• at a computing platform comprising at least one processor, a communication interface, and memory:
• generating a cryptographic key pair comprising a public key and a private key;
• publishing, to a server, the public key;
• generating a short message service (SMS) message;
• and
• signing, using the private key, the SMS message, wherein signing the SMS message comprises 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, and wherein signing the SMS message further configures the SMS message for validation using the cryptographic hash and the public key.

One or more non-transitory computer-readable media storing instructions that, when executed by a computing platform comprising at least one processor, a communication interface, and memory, cause the computing platform to:

• generate a cryptographic key pair comprising a public key and a private key;
• publish, to a server, the public key;
• generate a short message service (SMS) message;
• and
• sign, using the private key, the SMS message, wherein signing the SMS message comprises 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, and wherein signing the SMS message further configures the SMS message for validation using the cryptographic hash and the public key.
