Title: Innovations of Xinxing Hu in Cryptography

Introduction

Xinxing Hu is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of cryptography, holding 2 patents that showcase his innovative approaches to secure communications.

Latest Patents

One of his latest patents is focused on secure key delivery. This invention provides methods for encrypting communications that go into and out of devices, such as chips or proprietary buses. The encryption process occurs in a central Root-of-Trust (RoT), which includes agents for individual communication protocols. These agents generate session keys used to encrypt communications for specific sessions. The data is then sent to a crypto engine for the respective communication protocol. A key tunnel unit is utilized to receive a wrapped session key over a public bus, unwrapping it in hardware before transmitting the unwrapped session key to the corresponding crypto engine. This process ensures that the session key remains secure and is not exposed to software executing outside the RoT. The inline crypto engine can then use the session key to encrypt session data for transmission to another device or destination.

Another notable patent by Xinxing Hu involves comprehensively obfuscated cryptographic accelerators and operations. This invention describes apparatuses, systems, and techniques for performing cryptographic operations using multiple iterations. Each iteration consists of two or more stages operating in parallel on inputs derived from a common value. One stage computes real data while other stages compute dummy data, enhancing the security of the cryptographic process.
