X.509 Public Key Infrastructures (PKIs) are widely used for managing X.509 Public Key Certificates (PKCs) to allow for secure communications and authentication on the Internet. PKCs are issued by a trusted third-party Certification Authority (CA), which is responsible for verifying the certificate requester’s information. Recent developments in web PKI show a high proliferation of Domain Validated (DV) certificates but a decline in Extended Validated (EV) certificates, indicating poor authentication of the entities behind web services. The ACME protocol facilitates the deployment of Web Certificates by automating their management. However, it is only limited to DV certificates. This paper proposes an enhancement to the ACME protocol for automating all types of Web X.509 PKCs by using W3C Verifiable Credentials (VCs) to assert a requester’s claims. We argue that any CA’s requirements for issuing a PKC can be expressed as a set of VCs, returned in a Verifiable Presentation (VP). We propose a generic communication workflow to request and present VPs, and provide proof-of-concept of the feasibility of our approach.
