Secure Firmware Updates for Constrained IoT Devices Using Open Standards: A Reality Check

IEEE Access, 2019
While the IoT deployments multiply in a wide variety of verticals, the most IoT devices lack a built-in secure firmware update mechanism. Without such a mechanism, however, critical security vulnerabilities cannot be fixed, and the IoT devices can become

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

IBU: An In-Block Update Address Mapping Scheme for Solid-State Drives

IEEE Access, 2022
One of the most important features of solid-state drives (SSDs) is the ability to update data sectors out of place, performing garbage collection operations within its physical blocks, to mitigate limited flash memory lifespan. In SSDs, a firmware called

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

Advanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

Remote firmware update for constrained embedded systems [PDF]

2014 37th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2014
In this work, we present the architecture of firmware software update infrastructure, which uses a centralized server to distribute adequate firmware updates to a large number of embedded devices. These updates enable transparent proactive management of everyday bugs and other vulnerabilities inherent in software-based systems, as well as embedded ...
