Overview
ntAES128 core implements the NIST FIPS-197 Advanced Encryption Standard and can be programmed to either encrypt or decrypt 128-bit blocks of data using a 128-bit, 192-bit or 256-bit key. The ntAES128 has been carefully designed for high throughput applications with optimal logic resources utilization. The encryptor core accepts a 128-bit plaintext input word, and generates a corresponding 128-bit ciphertext output word using a supplied 128, 192, or 256-bit AES key. The decryptor core provides the reverse function, generating plaintext from supplied ciphertext, using the same AES key as was used for encryption. The hardware roundkey expansion logic has been designed as a discrete building block. This allows either to build a complete stand-alone AES solution, or to save logic resources by leaving the key generation process to the user. Alternatively, the roundkey expansion logic can be shared between multiple encryption/decryption cores for optimal silicon area resources utilization. The implementation is very low on latency, high speed with a simple interface for easy integration in SoC applications.

The cybersecurity threat landscape is dynamic and rapidly evolving. Indeed, attackers are constantly finding new ways to exploit critical vulnerabilities across a wide range of applications and devices. Protecting data and devices requires secure processes running on systems and networks.
The transition to post-quantum cryptography (PQC) has moved from research planning to operational execution. Federal policy, emerging procurement requirements, and evolving security standards are accelerating the adoption of quantum resistant cryptography across government and critical infrastructure systems.
The goal of this white paper is to provide a primer introduction to RoT and how to choose a right RoT as the trust anchor for a novel hardware based security architecture
A Root of Trust is the foundation on which all secure operations of a computing system depend. It contains the keys used for cryptographic functions and enables a system-wide secure boot process. It is inherently trusted and therefore must be secure by design.
