PKI applications

The PKI technology can meet security requirements of online transactions. As an infrastructure, PKI has a wide range of applications. Hewlett Packard Enterprise's PKI system can provide certificate management for IPsec and SSL.

The following are some application examples.

VPN

A VPN is a private data communication network built on the public communication infrastructure. A VPN can use network layer security protocols (for example, IPsec) in conjunction with PKI-based encryption and digital signature technologies for confidentiality.

Secure emails

PKI can address the email requirements for confidentiality, integrity, authentication, and non-repudiation. A common secure email protocol is Secure/Multipurpose Internet Mail Extensions (S/MIME), which is based on PKI and allows for transfer of encrypted mails with signature.

Web security

PKI can be used in the SSL handshake phase to verify the identities of the communicating parties by digital certificates.
