Identifying / Authenticating: the people / entities we communicate with are who they really say they are.
Privacy: The data is held confidential in your email or transaction. Only the intended sender and recipient can read and understand it.
Integrity: data is not inadvertently or intentionally manipulated on the way within the message or transaction without the involvement of all parties being conscious of the manipulation.
Non-repudiation: The sender can not refuse to send the transaction or message, and it can not be denied to the recipient.
Access Control: Only the designated individual or entity has access to protected data.
Through public key infrastructure (especially digital certificates), all of the above safety characteristics can be accomplished and enforced.
