PORT DRIVEN AUTHENTICATION IN A TDMA BASED NETWORK

摘要

A method for authenticating a message in a time division multiple access network is provided. The method includes; receiving a message from a node at an active relaying component (e.g. guardian); modifying the message and forwarding it to other nodes; receiving the modified message from the active relaying component; inspecting the value in the message inserted by the active relaying component; and comparing the value with an expected value based on a transmission schedule.
