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 workstation) and the responder (printer or server). To send encrypted data
to the printer, the workstation 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 used to send IP Sec encrypted data over the TCP/IP network to the printer.
Providing additional security in the negotiating process, SSL (Secure Sockets Layer protocols) are used
to assure the identities of the communicating parties with digital signatures (individualized checksums
verifying data integrity), precluding password guessing by network sniffers.
