The now-mature public key infrastructure (PKI) calls for a centralized, hierarchical system of certificate authorities that issue digital certificates for securing web sites and Internet communications, creating digital signatures, and several other purposes.
Remme moves these certificate management functions to its decentralized blockchain. As a result, various entities can issue end-user certificates using their own know-your-customer mechanisms without having to call upon a central certificate authority.
Such end-user certificates can serve as one of the factors in two-factor authentication, thus removing the need for passwords when interacting securely with a bank or other company that issues Remme certificates.
In addition, Remme’s approach removes the need for certificate revocation lists, the most awkward and difficult to manage part of PKI, because any revocation would automatically appear across all nodes. Thus any node on the blockchain can validate a certificate.
