Network coding has shown a considerable improvement in terms of capacity and robustness compared to traditional store-and forward transmission paradigm. However, since the intermediate nodes in network coding-enabled networks have the ability
to change the packets en route, network coding-enabled networks are vulnerable to pollution attacks where a small number of
polluted messages can corrupt bunches of legitimate messages. Recently, research effort has been put on schemes for protecting the
transmitted messages against data pollution attacks. However, most of them cannot resist tag pollution attacks. This paper presents
a new homomorphic MAC-based scheme, called Dual-Homomorphic MAC (Dual-HMAC), for network coding-enabled wireless
sensor networks. The proposed scheme makes use of two types of tags (i.e., MACs and D-MACs) to provide resistance against data
pollution attacks and partially tag pollution attacks. Furthermore, our proposed scheme presents low communication overhead
and low computational complexity compared to other existing schemes.
