4.5.2.2  Private Key Protection

A private key holder is responsible for taking all adequate precautions to secure their primary key and ensure that no one has access to it. This is important because anyone who obtains a user’s private key can forge a message and claim it was sent by that user, and can decrypt any sensitive communications encrypted by that user’s public key.

This includes all the common precautions you might expect, like:

  • Not including the private key in email.

  • Not exposing it in a readable environment.

  • Not writing one’s PIN on the back of the smartcard holding the key.

… and also involves educating users about the potential for social engineering attempts to acquire their private key, much as they are educated (we hope) not to give out their network passwords.
