Abstract
Techniques are disclosed for managing one or more public keys used for verification of one or more messages transferred over a communication network associated with a public warning system. In one example, a method comprises the following steps. A computing device of a communication network obtains key material for at least one source of a message generated for a public warning system. The computing device also obtains an identity of the source. A public key is computed by the computing device from the key material and the identity of the source. The public key is thus useable by the computing device to verify a message received from the source that is digitally signed using a corresponding private key of the source. In one example, the computing device comprises user equipment.
