A method of operating a radio receiver device is provided. The method comprises receiving a radio signal comprising an encrypted advertising packet, said advertising packet comprising a header portion and a payload portion comprising one or more encrypted payload structures. A decryption operation is performed using a decryption key on a first section of the payload portion and a length of a first payload structure of the payload portion indicated by the decryption result is determined. The indicated length of the first payload structure is compared to a set of feasible lengths based at least partially on the length of the payload portion. If the length of the first payload structure is not in the set of feasible lengths for the first payload structure, it is determined that the decryption key does not correspond to the advertising packet.
