Abstract
A routing device including a memory and a processor. The memory stores instructions. The processor is configured to execute the instructions to receive a signed route origin authorization (ROA), which includes a blockchain hash, and a border gateway protocol (BGP) update message, which includes one or more routes. The processor is further configured to implement a Route Origin Validation (ROV) process using the blockchain hash in the signed ROA to determine whether the one or more routes in the BGP update message are valid; update a routing table to include the one or more routes from the BGP update message when the one or more routes are determined to be valid by the ROV process; and refrain from updating the routing table with the one or more routes from the BGP update message when the one or more routes are determined to be invalid by the ROV process.
