Configuring Ssl/Tls - Ricoh SP 4510DN User Manual

Configuring SSL/TLS

Configuring the printer to use SSL/TLS enables encrypted communication. Doing so helps prevent data
from being intercepted, cracked or tampered with during transmission.
Flow of SSL/TLS encrypted communications
1. To access the printer from a user's computer, request the SSL/TLS device certificate and public
key.
2. The device certificate and public key are sent from the printer to the user's computer.
3. The shared key created with the computer is encrypted using the public key, sent to the printer,
and then decrypted using the private key in the printer.
4. The shared key is used for data encryption and decryption, thus achieving secure
transmission.
Configuration flow when using a self-signed certificate
