%X Current solutions for pollution attacks require a public key infrastructure support, but this is not desirable for the mobile Ad hoc networks. Therefore, this paper proposed the network coding scheme without public key infrastructure. This scheme could better prevent such pollution attack. It allowed the packets mutual verification, and thus an intermediate node could decide whether these packets could be encoded together without authenticating the source. Analysis and comparison of other signature schemes, the results show that this network coding without public key signature function is sufficient to prevent pollution attacks.
