Abstract: 
In this paper, we investigate a simple but effective coding mechanism, namely Coding
Opportunistically (COPE) [1], and the privacy violations which are likely to happen to COPE.
The COPE data, from the source node through the network to its destination node, can be easily
learned by the surrounding nodes, particularly, intersecting nodes and neighbour nodes. This
leads to a serious consequence in leaking the node identity and its private data. In order to cope
with the mentioned issues, we can apply cryptographic schemes. However, the security solutions
often exploit the public key schemes which nowadays run more slowly and give the longer
encrypted values as the effects of the key size increase to guarantee the algorithm complexity.
Hence, while the coding mechanism aims to decrease the bandwidth consumption by
aggregating (i.e., coding) multiple packets in the network, the security solutions increase the
data quantity. However, a necessary needs of combining data coding mechanism and
cryptographic algorithm is raised for both preserving privacy and optimizing bandwidth use at
the same time as mentioned above. In this paper we thus propose SCOPE, a lightweight privacy
preserving approach able to support nodes running the COPE protocol in a secret way, by
adopting the Elliptic Curve Cryptography (ECC) homomorphic encryption algorithm. The
proposal’s effectiveness and efficiency are proved through a variety of experiments.
