An encrypted communication system includes on-board devices configured to perform encrypted communication with a server located outside a vehicle. Each of the on-board devices includes an encrypted communication portion configured to perform encrypted communication with the server using an encryption key unique to a corresponding one of the on-board devices and a priority setting portion configured to set priority ranks of the on-board devices for encrypted communication. When each of the on-board devices performs encrypted communication with the server and if any one of the on-board devices is set to a higher priority rank, the on-board device is configured to perform encrypted communication with the server via the encrypted communication portion of the on-board device having the higher priority rank.
