| Summary: | 碩士 === 國立臺灣科技大學 === 資訊管理系 === 107 === The rapid growth of IoT devices in past few years brings convenience
in human life. The huge amount of installed IOT devices makes the device
manufacturer (vendor) difficult to maintain the IoT devices. One way
to maintain the IoT device is through the firmware update. Vendor can
add new functionality, enhance the security and re-configure the IoT device
through a firmware update. However, the firmware update process
is not without risk. There are several well-known attacks those targets the
firmware update process. In this thesis, we propose a robust and lightweight
framework that ensure the firmware update security using skipchain technology.
Utilizing the skipchain’s forward link, the proposed protocol can
do peer-to-peer firmware update verification efficiently. A prototype based
on the proposed framework is constructed and evaluated. Moreover, our
proposed framework is also proven to be secure and could withstand some
well-known attacks.
