Cryptographic Ignition Keys: Implementation Methodology and Guidance
This white paper explains the purpose and functionality of a Crypto-Ignition-Key, also known as a CIK. The white paper also discusses the benefits of using a CIK, including how a CIK can be used to increase the security of a communications device. It also provides detail on how to integrate a CIK into an embedded design.
How to Interface a USB Flash Drive to a Microcontroller
Although USB flash drives are easy to use, designing an microcontroller-based embedded system that supports a removable USB flash drive can be a challenging task. This white paper gives an overview of USB and highlights several USB host design options that will support the use of a USB flash drive. The paper discusses some of the design considerations for the USB connectors, power supplies and PCB. It is chock-full of links to helpful resources to make sure your microcontroller-based embedded system design will successfully interface to a USB flash drive.
Portable Memory Choices
This white paper examines the pros and cons of various portable memory options available to embedded system designers, including: consumer memory devices (e.g. USB flash drives and SD cards)--including "industrial" versions (e.g. industrial SD cards and CompactFlash cards), as well as OEM portable memory systems.
Removable Memory Key to IoT Firmware Updates
What is the best way to update the firmware of remote IoT (Internet of Things) devices? Over The Air (OTA), of course! What is the best way when OTA fails? With IoT devices that use mobile/cellular communications, it is critical to have a good Plan B for firmware updates. This white paper explores various methods of updating firmware when OTA fails. The benefits of using removable memory for manual firmware updates and other functions are discussed. The paper also explores why OTA updates fail and provides helpful hints to maximize OTA update success.
Wireless Coexistence: Pairing Wireless Medical Devices
The white paper, Wireless Coexistence: Pairing Wireless Medical Devices, examines the concept of wireless coexistence and provides four methods for intentionally linking or pairing two or more devices to prevent unintentional cross-talk. The method of using a removable, non-volatile memory device to transfer device ID information between transmitter and receiver is examined in detail, and a case study showing how Stryker Endoscopy utilized this method for the wireless transmission of high-definition video is also included.
