Abstract
Embodiments herein relate to a method performed by a network node for enabling verification of a broadcast message transmitted from the network node to a wireless device. The network node signals a first public key, to the wireless device, using a secure connection. The network node further transmits a first broadcast message protected by a signature. The signature is generated from at least a protected part of the first broadcast message using a first private key, the first private key being associated with the first public key. Thereby, the broadcast message can be verified by the wireless device using the distributed first public key, thus preventing fake broadcast messages to be accepted by the device.
