Public Key Infrastructure (PKI) is an encryption and cybersecurity architecture for managing digital certificates and communication encryption. PKI can be used to ensure secure electronic transfer, provide authentication for communications requiring data integrity and stringent proof of identity. The public/private keys created as part of PKI digital certificates can be used to provide a variety of very useful security services including digital signatures and non-repudiation.

As the CSO, you've been asked to brief the management team on how digital signatures and non-repudiation can be provided through a PKI and what the potential benefits to their use would be.
