Working Principle

The ATECC108A-SSHDA-T integrated circuit works by combining the powerful security architecture and protocols of the chip with an on-chip root of trust and cryptographic key storage. The chip supports a range of cryptographic algorithms, including elliptic curve cryptography (ECC), Advanced Encryption Standard (AES), Hash algorithm SHA-256/384, and Digital Signature Algorithm (DSA). The chip employs an integrated hardware random number generator (RNG) to ensure a secure and reliable level of randomness for the cryptographic operations.

The chip is secured with a root of trust, which is the first stage of code execution, followed by the code signing protocol. Code signing is used to verify the authenticity of code loaded onto the device. With code signing, each piece of code is digitally signed with a secure cryptographic signature. Any code that is not signed or not verified by the root of trust is immediately rejected and not executed on the device. This ensures that only signed code can be loaded and that malicious code cannot be loaded onto the device. The chip also supports authentication protocols and encryption protocols, including TLS, SSH, SSH-C, and IPsec. The chip\'s advanced security features help to prevent physical attacks by ensuring the chip\'s integrity and preventing the interception of sensitive data.

ATECC108A-SSHDA-T offers a range of additional features, such as secure storage of keys and other data, secure boot capability, secure hardware-enforced hardware-based cryptographic algorithms, tamper-resistant non-volatile memory, diagnostic features, power-savings features, data privacy with masking, encryption/decryption of data, access control to authenticated memory, and more.

Conclusion

The ATECC108A-SSHDA-T integrated circuit is a specialized IC designed with advanced features to provide secure authentication, encryption, and secure storage. Its comprehensive security features and efficient power management make it a suitable choice for developers of secure and power-efficient products and systems. The chip offers a secure, versatile, and low-power solution for applications requiring high levels of security and physical space efficiency.
