Application: Owner revocation emulation container (Patent ID: US20240152620A1)
The patent filed by Microchip Technology Inc. describes a device with a processor and boot code that can create revocation emulation containers for different owners of the device, each containing asset revocation information. This information is used to determine whether to revoke the use of specific assets associated with each owner. The asset revocation information is programmed in a one-time-programmable manner, ensuring that it cannot be modified after programming. The device uses unique private keys and signatures to verify the revocation emulation containers and subsequently revoke assets based on predetermined criteria.
Furthermore, the device includes a non-volatile memory and a static random-access memory (SRAM) with a physically unclonable function (PUF) region. The boot code generates unique private keys based on owner information and SRAM PUF data, ensuring security and authenticity. The revocation process involves creating, storing, retrieving, and verifying revocation emulation containers for each owner, allowing for the subsequent revocation of assets associated with those owners. Overall, the system provides a secure and efficient method for managing asset revocation in electronic devices over time, ensuring the protection of valuable assets such as cryptographic keys, executable images, and hash tables.
