SECURE COMMUNICATION IN A WIRELESS NETWORK

摘要

According to an example aspect of the present invention, there is provided a method comprising, receiving at least a first encrypted part of a coded data message from a first network node and a second encrypted part of the coded data message from a second network node, decrypting the first encrypted part of the coded data message using a first security key, wherein the first security key is generated based on a subset of a first channel matrix estimated by the terminal, decrypting the second encrypted part of the coded data message using a second security key, wherein the second security key is generated based on a subset of a second channel matrix estimated by the terminal and compiling the coded data message by combining at least the decrypted first part and the decrypted second part.
