BB-PKI: Blockchain-Based Public Key Infrastructure Certificate Management
2020 IEEE 22nd International Conference on High Performance Computing and Communications; IEEE 18th International Conference on Smart City; IEEE 6th International Conference on Data Science and Systems (HPCC/SmartCity/DSS), 2020Recently, real-world attacks against the web Public Key Infrastructure (PKI) have arisen more frequently. The current PKI that use Registration Authorities/Certificate Authorities (RAs/CAs) model suffer from notorious security vulnerabilities.

A Complete Study of P.K.I. (PKI’s Known Incidents)
Social Science Research Network, 2019In this work, we report on a comprehensive analysis of PKI resulting from Certificate Authorities’ (CAs) behavior using over 1300 instances. We found several cases where CAs designed business models that favored the issuance of digital certificates over ...
