ATSHA204-SH-CZ-T Specialized ICs: Application Field And Working Principle

The ATSHA204-SH-CZ-T is a specialized integrated circuit (IC) made for securely storing and authenticating credentials in secure applications. This secure IC is designed to meet the highest standards of security, including the FIPS PUB 140-2 level 3 criteria. It is well-suited for applications in secure data storage, secure firmware update, secure authentication, and secure communication in the Internet of Things (IoT) world.

Application Field

The ATSHA204-SH-CZ-T is mainly used in data security applications where secure authentication and data encryption are required. The authentication on this secure IC takes place using a variety of algorithms and techniques, such as symmetric and asymmetric key distribution, digital signature algorithms, and one-time-password (OTP) authentication.One of the main applications of the ATSHA204-SH-CZ-T is to secure authentication credentials in authentication-as-a-service (AaaS) offerings. This IC is being used to authenticate secure gateway access and remote access exchanges, as well as to authenticate access to enterprise applications, cloud storage systems, and mobile devices. The ATSHA204-SH-CZ-T is also becoming essential for securely storing and authenticating credentials in secure control access applications.In addition, the ATSHA204-SH-CZ-T is being used in secure data communication systems, such as those found in the world of the Internet of Things (IoT). This secure IC is being used to authenticate smart home devices, as well as to authenticate and secure data communication between connected devices.

Working Principle

The ATSHA204-SH-CZ-T is an 8-pin IC (integrated circuit) that functions like a crypto processor. It supports an array of different authentication algorithms and can securely store authentication credentials.The secure IC stores an authentication credential, such as a digital certificate or an authentication token, in device memory. The stored information is used in the authentication process to generate an authentication token or digital signature.During an authentication process, the ATSHA204-SH-CZ-T calculates a unique reference value using the stored authentication credential, the requesting credentials or data, and an algorithm. The resulting reference value is compared to a reference value stored inside the secure IC. If the two match, the authentication is successful.The ATSHA204-SH-CZ-T can also use asymmetric key distribution to authenticate itself. In this case, the secure IC compares a received set of public/private keys with a set stored inside the secure IC. If the two sets match, authentication is successful.

Conclusion

The ATSHA204-SH-CZ-T is a specialized IC designed for securely storing and authenticating credentials in secure applications. This secure IC meets the highest standards of security, making it ideal for applications in secure data storage, secure firmware update, secure authentication, and secure communication in the Internet of Things world. The ATSHA204-SH-CZ-T authenticates based on a variety of algorithms and techniques, such as symmetric and asymmetric key distribution, digital signature algorithms, and one-time-password (OTP) authentication.
