Block Diagram
The built-in authentication microcomputer stores the matching key data and accurately transmits the authentication results.
Security is enhanced by encrypting data transfers between the system and individual components.
Unauthorized access is prevented by the strong anti-tampering function incorporated into the authentication microcomputer.
Uses a secure communications protocol to verify the identity of devices attempting to
establish a connection.
Strong anti-tampering function prevents unauthorized access to the authentication
microcomputer.
Fast encryption processing function supports rapid data encryption and decryption.
Built-in EEPROM non-volatile memory for storing data and programs.
Slim security IP core for a compact package.
A variety of encryption libraries (DES, 3DES, and MISTY public key encryption,
etc.) are available.
Support for the development of necessary software.

Security Measures
Forgery
Fraud
Data Destruction
Requiring authentication in order to connect makes it possible to verify the reliability of equipment and component
Highly confidential data, such as personal information and product parameters, can be stored in encrypted form.
Anti-tampering functions similar to those used in smart cards can be used to prevent unauthorized deciphering of data.
Elevated Security
In the age of ubiquitous networking,
everyone
is linked
everywhere,
all the time.
In a networked society,
security threats
including forgery, fraud, and data loss are numerous and varied.
Security means limiting access to
specific persons, in specific places, at specific times.
