However, PKI is exposed to risks due to potential failures of Certificate Authorities (CAs) that may be used to issue unauthorized certificates for end-users. Many recent breaches show that if a CA is compromised, the security of the correspond- ing end-users will be in risk. As a solution to overcome such problems, Blockchain technology potentially addresses the problems of conventional PKI systems: avoiding a single point-of-failure and rapid autonomous auditable functions for CAs shortcomings, namely in certification-chaining revocations, as well as, issuing, endorsement or invalidation operations. By using a proper BFT-Enabled Blockchain under fully decentralized ledgered and resilient signatures, we can design novel PKI framework foundations, with the ability to store and manage digital certificates within a public and immutable ledger.
