The next-generation communication technology has to address a large number of devices demanding high quality of services. Network Coding seems to be a promising solution to achieve this in the mobile small cell environment. However, network coding itself comes with specific security challenges which affect the efficiency expected to achieve by employing network coding. Pollution attacks, where malicious intermediate nodes pollute the packets in communication, is one of the major hindrances to the practical implementations of network coding. Even though security schemes are proposed against pollution attacks, secure network coding enabled mobile small cell architecture needs a lot of advancements from the present state of the art. This paper investigates the existing security architectures and proposes a secure network coding architecture that incorporates blockchains to support efficient integrity schemes against pollution attacks.
