In China, the industrialization of reverse engineering has become one of the main factors affecting innovation. For innovative enterprises in addition to the use of legal means to protect their own interests, hardware encryption is also a good choice. GIANT-1 security chip from ICTK provides a new hardware encryption solution for firmware protection, which protects firmware from illegal copying and tampering.
In embedded system, although the choice of encryption algorithm is equally critical, the key security is the most important. To ensure the security of the key, the key should never leave the boundary of the embedded system, otherwise the attacker may break the security barrier of the device. The most secure way is to keep the key in a dedicated hardware security chip, which ensures that the key will not be exported through the hardware security chip protection, and realize data encryption and authentication through the interaction between the security chip and the master control chip.
Advantages:
1. The real device key is encrypted by VIA PUF and stored in the GIANT-1 chip. It will be decrypted and restored when used to ensure the security of the key.
2. Each chip generates a different key. The PUF KEY used to protect the KEY is a unique physical feature of the chip. Each chip is different and cannot be cloned.
3.GIANT-1 built-in anti-bypass attack function and true random number generator TRNG, to prevent violent cracking attacks.
