AT83C26-RKTUL is a tamper-resistant access control IC solution, integrated with a two-level secure authentication scheme, encryption engine, and a nonvolatile EEPROM configuration memory, which is designed to protect access to sensitive application areas. In this article, we will discuss the application field and working principle of AT83C26-RKTUL.

Application field

AT83C26-RKTUL is ideal for access control applications such as smart cards, non-volatile authentication tokens, and secure physical access control cards. It provides tamper-resistant protection against unauthorized access and ensures the secure handling of sensitive customer data.

The AT83C26-RKTUL integrated tamper detection and protection feature provides powerful protection for customer/user credentials by using an external tamper resistant key-authentication. This provides an extra layer of security to ensure the secure handling of sensitive customer data. The external key-authentication also helps to ensure that the customer\'s credentials are protected from brute-force attacks and replay attacks.

AT83C26-RKTUL is also suitable for use in other applications where secure authentication is required, such as secure web portals, secure digital signatures and secure biometric authentication.

Working principle

AT83C26-RKTUL utilizes a two-level secure authentication scheme, which includes a Master Key that is used to authenticate the user and a Secure Key that is used to generate and validate the User Token. The Master Key is securely stored in the nonvolatile EEPROM configuration memory of the AT83C26-RKTUL. While the Secure Key is generated on the fly by the AT83C26-RKTUL for each authentication cycle. The Secure Key is a random number, which is generated by the AT83C26-RKTUL using its built-in random number generator.

Once the Master Key and the Secure Key have been generated and authenticated, the AT83C26-RKTUL will generate an encrypted User Token. This encrypted User Token will then be sent to the user/customer to authenticate their access to the application. The encrypted User Token is generated using an advanced encryption algorithm, which is designed to protect the user’s credentials from replay attacks.

Once the user has successfully authenticated themselves, the AT83C26-RKTUL will then validate the token and allow access to the application. The AT83C26-RKTUL will also apply tamper protection mechanisms, which will detect any tampering attempts and alert authorized personnel.

In addition to the two-level secure authentication scheme, the AT83C26-RKTUL also provides secure memory management, which ensures privacy and prevents unauthorized access to stored credentials. The AT83C26-RKTUL also provides secure communication links that enable secure biometric authentication, digital signature, and transmission of encrypted data.

Conclusion

To conclude, the AT83C26-RKTUL offers a comprehensive solution to protect access control applications such as smart cards, authentication tokens, and physical access cards. With its two-level secure authentication scheme, advanced encryption algorithm, and tamper protection features, the AT83C26-RKTUL is an ideal choice for organizations that require secure access control to sensitive applications or data.
