Abstract

For achieving packet authentication according to an applicable security policy between a sending node (903) and a receiving node (902) in a network, the following steps are taken:the transformations occurring to a packet en route between the sending node and the receiving node are discovered dynamically (1003, 1004),the discovered transformations are checked (1004) to be acceptable based on the applicable security policy, andthe dynamically discovered, acceptable transformations are compensated for (1004, 1006) before authenticating packets transmitted from the sending node to the receiving node.
