A Mobile Ad-hoc NETwork (MANET) is an autonomous system of mobile nodes connected by wireless links. MANET are characterized by open, distributed and dynamic architectures, built on top of the shared wireless medium; all features contribute to make MANET very vulnerable to attacks at any layer of the Internet model. The authors consider the following problem: nodes in a MANET must separate data packet using rate less codes but some nodes are assumed to be malicious, i.e., before transmitting a coded packet they may modify its payload.
