PKIhallinta

PKIhallinta is a Finnish term that translates to Public Key Infrastructure management. It refers to the set of policies, processes, people, and systems required to create, manage, distribute, use, store, and revoke digital certificates. PKIhallinta is crucial for establishing trust in electronic transactions and communications, enabling secure authentication, data encryption, and digital signatures.

The core components of a PKI include a Certificate Authority (CA), Registration Authority (RA), certificate repository, and end-entity certificates. The CA is responsible for issuing and revoking digital certificates, while the RA typically handles the verification of identities before a certificate is issued. The certificate repository stores issued certificates and their status, allowing users to verify the validity of a certificate. End-entity certificates are issued to individuals, devices, or organizations to uniquely identify them.

Effective PKIhallinta ensures the integrity and confidentiality of sensitive information. It is widely used in various applications such as secure web browsing (SSL/TLS), secure email (S/MIME), virtual private networks (VPNs), and code signing. Proper management of a PKI involves robust security measures to protect the CA's private keys, regular audits, and clear procedures for certificate lifecycle management. Failure to implement strong PKIhallinta can lead to security breaches, identity theft, and a loss of trust in digital systems.
