Dual-Homomorphic Message Authentication Code Scheme for Network Coding-Enabled Wireless Sensor Networks

Abstract

Network coding has shown a considerable improvement in terms of capacity and robustness compared to traditional store-andforward 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.

“…The proposed security scheme is closely comparable with [13] and Dual HMAC schemes [14], [20] which already are well known and secure. However, we provide an advantage over the computational and communication overhead of these schemes at the expense of a blockchain facilitated over the network.…”

“…However this is again a part of the message and hence negligible comparatively to the total overhead. Even if we consider the same number of tags for the Dual HMAC scheme [20], it needs additional L tags to protect against the tag pollution attack making our scheme approximately L/(L + L ) times efficient in terms of communication overhead.

“…Additionally, the tags will be sent to the central unit via control channel which is independent from the communication channel between the devices. Comparing this scheme with other schemes secure against tag pollution attacks, we understand that for the same number of tags, our scheme produces a much lesser communication overhead compared to Dual HMAC [14] and MacSig [12]. Fig.…”

“…MacSig [12] proposes the usage of a homomorphic signature over the MAC scheme to certify that the tags attached to the packets are corresponding to the packet itself. Dual HMAC and HMAC [13,14] try to reduce the computational and communicational overhead of MacSig using a novel key distribution model based on c cover free family. This also provide security against a situation in which a number of compromised nodes act together to pollute the network at a lower key storage overhead at intermediate nodes.…”

Key Management for Secure Network Coding-Enabled Mobile Small Cells

“…Data integrity is required to prevent any polluted data packets from being transmitted further through the network. The research community proposed various integrity schemes [24,25,26,27,28,29,30,31,32,33,34] to solve this problem. However, the efficiency and effectiveness of the integrity schemes are closely related to the key management schemes which are responsible for the generation, distribution, use and update of the cryptographic keys used by the integrity schemes.…”
