Abstract: A server includes a dedicated hardware card that is responsible for digesting an incoming email, appending a date and time to the digest to create a time stamp, and signing the result with a private digital signature. This provides a secure time stamp for an email that is resistant to falsification and tampering by the sender of an email, and which can be verified by a receipient of the email.
