The dis-tributed processing could have several advantages for wirelesssensor networks. First of all, in WSN computation is typicallymuch less energy consuming than communication. Secondly,in-network processing enables WSN to provide more com-plex services to application layer, and not only data gath-ering functionality. However, in addition to computationaloverhead, in-network data processing introduces also manychallenging security issues. Most of them are still open andrequire development of innovative security mechanisms. Inthis article we survey the current research related to secu-rity of in-network data processing in wireless sensor networksand highlight the directions, which are most promising in ouropinion.
