In addition to providing encryption functions that protect communications data, the Trusted Secure IP of the RX Family also protects the key that deciphers that encryption, and makes leaked communications data indecipherable, enabling safer communications for the coming 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 / theft of encryption keys
(the biggest feature of trusted secure IP)

 

 

RX65N/RX651 also support public key encryption and SHA, and can be used as an SSL communications accelerator.
