Abstract
Systems and methods discussed herein are directed to handling the transmission of emergency alert messages, such as wireless emergency alert (WEA) messages, using a Public Key Infrastructure (PKI) made available to public networks and non-public networks (NPNs) as well as the computing devices (e.g., terminals, user equipment (UE), etc.) operating on the public networks and/or NPNS. The emergency alert messages may be transmitted and/or presented using cryptographic signatures generated by private key and/or public keys associated with the PKI.
