AI summary

Systems and methods for secure device onboarding in cellular networks by leveraging purposely induced authentication failures and device fingerprinting. A security platform, working in conjunction with the cellular network, detects an authentication failure triggered during a device's connection attempt. The platform then performs device fingerprinting based on data and/or signaling exchanged during the failed attempt. After successful fingerprint verification and completion of additional verification steps, the security platform enables the device's connection. This approach enhances security by verifying the device's identity beyond traditional SIM-based authentication, ensuring only authorized devices gain access. The invention encompasses various SIM card scenarios, including fixed-key SIMs and unique keys managed by the security platform, providing flexibility for different deployment models.
