In addition to providing encryption functions that protect communications data, the Trusted Secure IP of the RX Family of 32-bit microcontrollers (MCUs) also protects the key that deciphers that encryption, and makes leaked communications data indecipherable, thus enabling safer communications for the Internet of Things (IoT) age.

| Remarks | Basic block cipher | Traditionally used common key encryption | Public key encryption frequently used in SSL, etc. | Used for tamper detection, etc. | Generates unpredictable random keys | Prevents falsification of encryption keys | Prevents illegal use of encryption and theft of encryption keys (The biggest feature of Trusted Secure IP) | |
RX65N/RX651 microcontrollers also support public key encryption and SHA, and can be used as an SSL communications accelerator.
