Blockchain X.509 Certification Authority

Public Key Infrastructure (PKI) is the standard today to enable secure communication over the web, sign document or to encrypt sensitive data. PKI comprises digital certificates managed by the certificate authorities (CAs) to verify the user’s identity. However, the security of PKI is unfortunately reliant on the reliability of these third-party CAs. This serves as a single point of failure for PKI. Over the past, there have been several incidents of popular CA breaches, where the centralized operation model of CAs caused numerous targeted attacks due to the spread of rogue certificates.

With CodeB’s Blockchain based X.509 Certification Authority the becomes CA pool completely decentralized and at the same time remains compatible to with established PKI standards for effective real-world integration.

CodeB Nodes provide all the traditional X.509 PKI operations (i.e., registration, validation, verification, signing and revocation), making it compatible with existing PKI standards.

Below you see a short demonstration how a CodeB Blockchain Identity can issue a Self-Signed Certificate to sign a PDF document. As every CodeB includes a RFC 3161 compliant timestamping authority (TSA) the applied signatures can be time stamped right away.
