Patent ID: 11368450

Abstract:
The disclosure discloses a method for bidirectional authorization of a blockchain-based resource public key infrastructure, aiming at solving security threat problems that a legal BGP route is illegal and a legal IP address is blocked caused by malicious operations. A technical solution is as follows: constructing a blockchain-based resource public key infrastructure system RPKIB composed of a resource issuer, a resource transaction application client, a resource receiver and a blockchain network; changing any operation of issuing, revoking, overwriting and modifying of a resource certificate by the resource issuer into a bidirectional authorization mode, and implementing the operation of the resource certificate only when the issuer and the receiver both agree; and carrying out, by the issuer, operations of a resource certificate RC and route origin authorization ROA as transactions that are carried out through the blockchain network, and distinguishing whether the operations are malicious behaviors or normal operations.
