A method for providing communication in a power distribution communication network

The present invention concerns a method for providing secured communication in a power distribution communication network comprising a plurality of devices (101, 102). The method comprises to create a, in particular write protected, connection topology file (121, 122), to provide a message (130) comprising one or more identifiers (111a, 112a, 120a) related to data (111a ... 1xxx) included in the connection topology file (121) and to send (140) the message (130) comprising the one or more identifiers (111a, 112a, 120a) related to data (111 a ... 1xxx) included in the connection topology file (121, 122) from a source device (101) out of the plurality of devices (101, 102) of the power distribution communication network addressed to a destination device (102) out of the plurality of devices (101, 102) of the power distribution communication network. Further, the present invention concerns devices (101, 102) for the power distribution communication network each comprising a communication unit (1071, 1072) adapted to implement steps of the method for providing secured communication in the power distribution communication network.
