Abstract

According to an example aspect of the present invention, there is provided an apparatus configured to determine a first channel definition describing a first wireless communication channel between the apparatus and a second apparatus, the first wireless communication channel being on a first frequency band, determine a second channel definition describing a second wireless communication channel between the apparatus and the second apparatus, the second wireless communication channel being on a second frequency band which has a lower bound at a higher frequency than an upper bound of the first frequency band, and derive an encryption key at least partly based on the second channel definition, and use the encryption key to encrypt information before it is transmitted to the second apparatus over the first wireless communication channel.
