In adversarial environments, the security<br />becomes a crucial issue in wireless sensor networks (WSNs). There are various security<br />services in WSNs such as key management, authentication, and pairwise key<br />establishment. Due to some limitations on sensor nodes, the previous key establishment<br />techniques are unsuitable for WSNs. To overcome these problems, researchers propose<br />several key pre-distribution schemes. Our proposed approach uses a combinatorial<br />framework in the hypercube-based (HB) scheme to pre-distribute keys to each sensor<br />node. By this way, the number of common keys between two nodes in a wireless<br />communication range increases. Therefore, the level of security in terms of resilience<br />against node capture attack and the probability of re-establishing an indirect key will be<br />improved. https://jsciences.ut.ac.ir/article_62693_cba2efa457a241a1934f1d26aa09e9d7.pdf
