Get started with EdgeLock A5000 support package
The AN12402 describes how to leverage the EdgeLock A5000 ease- of-useconfiguration
for secure cloud onboarding to the Azure IoT Hub cloud platform. It provides detailed
instructions to run the software example provided as part of the support package using
an OM-A5000ARD and an i.MX 8M board with a Linux OS.
5.2.4.4 AN12403 - EdgeLock SE05x for Secure connection to IBM Watson IoT
The EdgeLock A5000 is designed to provide a tamper-resistant platform to safely store
credentials needed for device authentication and registration to public or private clouds.
EdgeLock A5000 helps to set up a trusted TLS connection to onboard devices to the
cloud without writing security code or exposing credentials or keys
The AN12403 note describes how to leverage the EdgeLock A5000 ease- of-use
configuration for secure cloud onboarding to the Watson IoT cloud platform. It provides
detailed instructions to run the software example provided as part of the support package
using an OM-SE050ARD and an FRDM-K64F board.

Table 9. Use case examples
5.2.5.1 AN12661 - EdgeLock SE05x for Wi-Fi credential protection
The EdgeLock A5000 allows you to authenticate devices attempting to connect to a Wi-
Fi router or wireless LAN network and, in this way, it helps secure access to restricted
networks. EdgeLock A5000 supports WPA-PSK and WPA-EAP-TLS security protocols.
In this case, the Wi-Fi module leverages EdgeLock A5000 to safely store the password
(in case of WPA-PSK protocol) or the private key and certificate (in case of WPA-EAP-
TLS authentication) that are used to establish the secure WiFi connection. During the
Wi-Fi connection setup, EdgeLock A5000 is also leveraged to derive the session keys
required for data exchange.
The AN12661 describes how to leverage EdgeLock A5000 for Wi-Fi credential
protection. It explains how to run a demo setup that showcases the use of EdgeLock
A5000 ease-of-use configuration to authenticate devices to a Wi-Fi network based on
WPA-EAP-TLS protocol.
5.2.5.2 AN12662 - Binding a host device to EdgeLock SE05x
The EdgeLock A5000 provides manufacturers the option to bind the MCU of the IoT
device to the secure element, so that security services offered by EdgeLock A5000 can
only be used by that particular MCU.
The AN12662 describes the different stages during the product manufacturing where the
binding process can be implemented, depending on the IoT device security requirements
and the available MCU
