FIELD FIRMWARE UPDATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17969916 titled 'FIELD FIRMWARE UPDATE

Simplified Explanation

The abstract describes a patent application related to field firmware update (FFU) technology. The invention involves a memory module that receives an encrypted segment of a firmware (FW) package associated with FFU. The memory module then stores a decrypted segment of the FW package and re-encrypts it before communicating it to another memory module.

  • The patent application relates to field firmware update (FFU) technology.
  • A memory module receives an encrypted segment of a firmware (FW) package associated with FFU.
  • The memory module stores a decrypted segment of the FW package.
  • The memory module re-encrypts the decrypted segment of the FW package.
  • The re-encrypted segment of the FW package is communicated to another memory module.

Potential Applications

  • This technology can be applied in various electronic devices that require firmware updates, such as smartphones, tablets, computers, and IoT devices.
  • It can be used in industrial equipment and machinery that rely on firmware for operation and require remote updates.
  • The technology can be implemented in automotive systems to facilitate secure and efficient firmware updates for vehicle components.

Problems Solved

  • The technology solves the problem of securely updating firmware in memory modules by encrypting and re-encrypting the FW package segments.
  • It ensures that the FW package remains protected during the update process, preventing unauthorized access or tampering.
  • The invention provides a reliable and efficient method for transferring FW package segments between memory modules.

Benefits

  • The technology enables secure and efficient field firmware updates, reducing the risk of vulnerabilities and improving device performance.
  • It allows for seamless updates without the need for physical access to the memory module, saving time and resources.
  • The re-encryption process ensures the confidentiality and integrity of the FW package, enhancing overall system security.


Original Abstract Submitted

Methods, systems, and devices related to field firmware update (FFU). A first memory of a memory module may receive an encrypted segment of a FW package associated with FFU. A decrypted segment of the FW package may be stored by the first memory. A re-encrypted segment of the FW package may be stored by the first memory. The re-encrypted segment of the FW package may be communicated to a second memory of the memory module.
