AT97SC3204-U2A1A-20 is a high performance, low-cost, non-volatile EEPROM-based secure microcontroller manufactured by Atmel that is designed for applications requiring secure authentication. It integrates a secure memory module with unmatched read/write performance and execute-in-place flash technology. The microcontroller also features an on-chip Cryptographic Coprocessor for executing algorithms for secure authentication.

Application Field

The AT97SC3204-U2A1A-20 can be used in a variety of applications that require secure authentication, including but not limited to: access control, secure access to confidential data, identification cards, smart grid systems, and embedded biometric authentication. Additionally, the integrated Secure Channel and On-chip Coprocessor allows for highly secure data transmission, providing even greater security and privacy.

Working Principle

The AT97SC3204-U2A1A-20 works through an authentication scheme known as authentication-by-observation. To begin, the device first generates a random number (R) and an associated observation (O). Then, the device checks the received data against a pre-stored public key (K). If the observations match the public key, then the device deduces that the data is authentic, and the authentication process concludes successfully.

To increase security, the device can also use a digital signature. This makes it considerably harder for fraudsters to bypass authentication by creating a false observation. The signature is created by taking the authentication data (R + O) and executing an algorithm designed to create a digital signature. Once again, the public key is used to verify the authenticity of the signature.

The AT97SC3204-U2A1A-20 also features an integrated Cryptographic Coprocessor. This allows the device to execute cryptographic algorithms such as DES and AES, providing even greater security and privacy in applications requiring authentication. Additionally, the device\'s on-chip secure memory module eliminates the need for external memory, further enhancing security.

Conclusion

The AT97SC3204-U2A1A-20 is a low-cost, secure microcontroller manufactured by Atmel that is designed for applications requiring secure authentication. It features an integrated Secure Channel and On-chip Cryptographic Coprocessor, allowing for highly secure data transmission and authentication. Additionally, the device integrates an on-chip secure memory module, eliminating the need for external memory. This makes the AT97SC3204-U2A1A-20 an ideal choice for applications requiring secure authentication.
