Data security
When you create a thing within AWS IoT Console, the associated SIM enables the Quectel BG96
module to register on a cellular network.
The Amazon Trust Service (ATS) uses the cellular network to securely deliver the following information
to the Quectel BG96 module.
For identification purposes:
•
The unique AWSthing name
•
The Amazon Resource Name (ARN) that defines which AWS endpoint supports the thing
For security purposes:
•
A set of X.509 certificates
•
An encrypted private key – AWS and the Quectel BG96 module use key pairs for signing data
The certificates and private key are stored in a secure Java keystore. The end user cannot see or handle
the security materials throughout their use.
When a thing is deleted in AWS, the data within the device keystore remains in the keystore. If you
reuse the device with a new SIM and recreate it as a new thing within AWS, then any existing security
information in the keystore is replaced by the new certificates and a new private key.
AWS security compliance
The Quectel BG96 module meets AWS security requirements:
•
Each connected device has a set of credentials to access the message broker or device shadow
service
•
Device credentials are stored safely in order to send data securely to the message broker
•
All traffic to and from AWS IoT is encrypted over Transport Layer Security (TLS)
For more information, see the AWS documentation Security section, including:
https://docs.aws.amazon.com/iot/latest/developerguide/iot-security.html.
Processing updates
Updates to the certificates and keys are handled in the same way as all security data. This enables you
to apply a managed certificate rotation policy, as well as automatically protecting the device against
changes in rootCA providers.
