PKIbasert
PKIbasert is a term used to describe information systems and security architectures that rely on Public Key Infrastructure (PKI) to manage cryptographic keys and digital certificates. In a PKI-based approach, authentication, data integrity, and non-repudiation are achieved through asymmetric cryptography and trusted certificate authorities.
A PKI consists of components such as Certificate Authority (CA), Registration Authority (RA), certificate repositories, and
Trust models vary in PKI-based environments. A hierarchical model uses root and subordinate CAs; bridge or cross-certification
Common uses of PKI-based approaches include securing web traffic with TLS certificates, email security with S/MIME,
Challenges include managing certificate lifecycles, revocation delays, key compromise, and the complexity of policy governance. Successful
