Public key infrastructure (PKI) enables the creation of a trusted environment for businesses wishing to conduct trade through an Internet solution.
Specifically, a digital certificate and the infrastructure under which the digital certificate is issued provide the information and structure needed to:
- minimise fraud by authenticating the identity of people via the Internet
- provide privacy of messages by minimising the risk that they can be read in transit, or by anyone, other than the intended recipient
- assure the integrity of electronic communications by minimising the risk of them being altered or tampered with in transit without the recipient being aware
- provide non-repudiation of transactions so that people cannot deny involvement in a valid electronic transaction.
