Multicast research has explored the security challenges faced in group communications. Multicast transport and multicast security need to work in close collaboration to realise a multicast service. However, there has been comparatively little work to combine the two technologies. In this paper the authors, presenting an example of partially integrating Timed Efficient Stream Loss-Tolerant Authentication (TESLA) protocol and the File Delivery over Unidirectional Transport (FLUTE) protocol. TESLA provides source authorization and data integrity for multicast groups. This paper proposes a loose synchronization mechanism for a unidirectional transmission environment, suited to satellite networks. It also analyses the effects on Forward Error Control (FEC) and the congestion control building blocks of FLUTE when used with TESLA.
