A method for authentication between at least two nodes within a network, preferably a wireless sensor network, is disclosed. The sending node computes a t-bit long hash value by using a hash function h. A transmission of possibly few additional data over the network is designed in such a way that from the sending node to the receiving node only t-k bits of the hash value are transferred as truncated hash value, whereby k is a fix but arbitrary natural number between 1 and t-1. The transmitted hash value is compared to a computed hash value at the receiving node.
