Introduction

Torsten Stein is a notable inventor based in Snohomish, WA (US). He has made significant contributions to technology, holding a total of 12 patents. His work primarily focuses on enhancing device security and provisioning.

Latest Patents

One of his latest patents is related to device provisioning. This invention involves equipping a device with a public/private key pair, where the private key is securely stored on the device. The public key is used to track ownership by manufacturers, vendors, and provisioning services. When a user purchases the device, a transaction involving the public key and the user is recorded. Provisioning services prepare a configuration payload specific to the user, which is encrypted using the device's public key. Upon powering on, the device decrypts this payload using its private key to adjust its configuration parameters.

Another significant patent is for a trusted cyber physical system. This invention features a brownfield security gateway that supports a trusted execution environment (TEE). It employs cryptographic and physical security to protect sensitive transmissions to controllable devices. The gateway can be implemented with a System on Chip (SoC) that filters content within a transmission. Once authorized, the transmission is forwarded to a trusted peripheral device, which then transfers it to the controllable device. This setup ensures that both the trusted peripheral and controllable devices are physically protected.
