Systems and methods for verifying a route taken by a communication

A method for verifying a route taken by a communication, the method comprising:

• obtaining a communication transmitted by a source entity, wherein:
• the communication includes data and digital signatures,
• each of the digital signatures is generated based on at least the data, and
• the digital signatures include:
• a digital signature associated with the source entity, and
• a set of digital signatures associated with at least a subset of intermediate entities on a route taken by the communication;
• verifying the digital signatures included in the communication;
• after obtaining the communication transmitted by the source entity, determining an expected route for the communication based at least in part on an identity of the source entity and a network map, the expected route for the communication comprising an expected order of entities from the source entity to a destination entity based at least in part on the network map;
• verifying whether the digital signatures included in the communication were included in the communication in the expected order as specified by the expected route for the communication;
• and
• processing the data;
• wherein the communication is in a JSON Web Token (JWT) format including a “payload” key-value pair and a “signatures” key-value pair, wherein a value of the “payload” key-pair includes the data, and a value of the “signatures” key-pair includes a value indicative of an order in which the digital signatures are included in the communication.

A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for verifying a route taken by a communication, the method comprising:

• obtaining a communication transmitted by a source entity, wherein:
• the communication includes data and digital signatures,
• each of the digital signatures is generated based on at least the data, and
• the digital signatures include:
• a digital signature associated with the source entity, and
• a set of digital signatures associated with at least a subset of intermediate entities on the route taken by the communication;
• verifying the digital signatures included in the communication;
• after obtaining the communication transmitted by the source entity, determining an expected route for the communication based at least in part on an identity of the source entity and a network map, the expected route comprising an expected order of entities from the source entity to a destination entity based at least in part on the network map;
• verifying whether the digital signatures were included in the communication in the expected order as specified by the expected route for the communication;
• and
• processing the data;
• wherein the communication is in a JSON Web Token (JWT) format including a “payload” key-value pair and a “signatures” key-value pair, wherein a value of the “payload” key-value pair includes the data, and a value of the “signatures” key-value pair includes a value indicative of an order in which the digital signatures are included in the communication.
