A method for authentication of elements of a group, especially for authentication of sensor nodes in a preferably wireless sensor network is disclosed. The group has one specific element—leading element—with which each of the group elements can exchange information and wherein the authentication of the group elements takes place with regard to the leading element. The leading element sends an authentication request to the group elements wherein the authentication request is the same for all the group elements. The group elements each send authentication responses—based on the authentication request—to the leading element, with the authentication responses being different for each group element.
