Newer implementations of KeyboxXml often involve nested encryption. The XML file itself might be encrypted with a transport key, while the payload inside is encrypted with a device-specific key. This "encryption-in-encryption" ensures that even if the file is intercepted during the provisioning process, it is useless without the device's physical TEE. Can’t copy the link right now
