Korean Keros encryption chip - Lite

Encryption chip - KEROS-Lite is a high-performance 64-byte OTP memory family with an advanced built-in AES 256 security engine and encryption functions.
Through dynamic, symmetric mutual authentication, data encryption, and data decryption, it provides a secure place for storing sensitive information in the system. With its protection circuit, this information remains secure even under attack.
KEROS-Lite also provides high security, low cost, and easy implementation for host-client type systems without requiring an MCU operating system. The embedded AES256 encryption engine provides dynamic, symmetric mutual authentication between the device and host, and encrypts all data and passwords exchanged between them. These operations can use separate AES256 key sets.
A simplified host library is provided to customers, and customers can easily access and handle KEROS-Lite.
