Configuration on a Computer
Confirm that the digital certificate being used by the printer to encrypt PDF and XPS files has been
imported and is registered on the recipient’s computer. This will assure the ability to conduct two way
digital signing of files, should this capability be desired or needed.
IP Sec
IP Sec (IP Security) is comprised of the IP Authentication Header and IP Encapsulating Security
Payload protocols, that secure IP communications at the network layer of the protocol stack, using
both authentication and data encryption techniques. The ability to send IP Sec encrypted data to the
printer is provided by the use of a public cryptographic key, following a network negotiating session
between the initiator (client computer) and the responder (printer or server). To send encrypted data to
the printer, the computer and the printer have to establish a Security Association with each other by
verifying a matching password (shared secret) to each other. If this authentication is successful, a
session public key will be built and used to send IP Sec encrypted data over the TCP/IP network to the
printer.
Providing additional security during the Public Key negotiating process, Digital Certificates can
alternatively be used in place of the Shared Secret, to encrypt the Public Key information being
exchanged between communicating parties. The Digital Certificate resides on the printer (managed as
stated in this Encryption section in the Configuring Scan File certificates topic) and must also have
been imported and stored on the computer that is encrypting data being sent to the printer.
