All data is exchanged in an encrypted format with a unique key for each connection. Private keys are never stored in the firmware of Edge devices or in the source code of our cloud platform. The private keys are generated by the manufacturer of the Crypto Element on the chip during production. We use the Crypto Element to store the network credentials of our devices, ensuring that they remain unreadable by third parties. This approach enhances the overall security of the system and mitigates the risk of unauthorized access to sensitive information.
