Computer Business Systems and automated business transactions require robust and rigorous security measures. Public key cryptography supports security mechanisms such as confidentiality, integrity, authentication and non-repudiation. A Public Key Infrastructure (PKI) is a foundation on which other applications, systems and Network components are built.
