Integrate the hierarchical cluster elliptic curve key agreement with multiple secure data transfer modes into wireless sensor networks

Since sensor nodes in wireless networks or Internet of things have limited resources, achieving secure data transmissions among is a challenge. Hence, efficient key management schemes with lightweight ciphers are essential. Many asymmetric keys public mechanisms been developed. However, they unsuitable for group communications networks, because usually devoid sufficient memory, CPU and bandwidth to deal complex operations. In addition, only few agreements integrated into transmissions. Therefore, agreement using the hierarchy-based cluster elliptic curve named HCECKA proposed this study networks. The presented security mechanism relies on curves instead logarithmic curves, utilises lesser length accomplish similar classification than Diffie-Hellman Rivest Shamir Adleman cryptosystems. Simultaneously, scheme provides rapid, dynamic synchronisation technique plenty no need reorganising whole system if members join leave
