Aiming at the problems of uneven levels of electronic authentication service capabilities and the difficulty of mutual recognition of digital certificates across industries, regions and businesses, this paper proposes a distributed collaborative certificate issuance and verification method based on the chain of trust. First, through an in-depth analysis of the problems of electronic authentication services, the goal of cross-domain trust management is proposed, and a cross-trust domain certificate mutual recognition model is designed; second, a comprehensive evaluation index of the certificate center is introduced, and a consensus mechanism based on the chain of trust is constructed; then, a collaborative certificate issuance and validation method based on the chain of trust is designed to effectively realize cross-domain certificate validation. Finally, the validation of the practical application of cross-domain collaborative certificates in electric power system proves the scientificity and reasonableness of the model and method proposed in this paper.
