MANAGEMENT OF PUBLIC KEYS FOR VERIFICATION OF PUBLIC WARNING MESSAGES

摘要

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 usable 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.
