Certain investigations on secure mobilization in wireless sensor networks

Abstract

Wireless Sensor Network (WSN) is a multi-hop self-organizing newlinenetwork with the intention of linking many nodes. Various sensor nodes are newlinepositioned and organized with other nodes for secure data communication. newlineSensor nodes observe the data transformation to a sink node. The network newlinecomprises various attacks such as black holes, sinkholes, wormhole attacks, newlineflooding attacks, and so on. Owing to the presence of attacks, secure routing is newlinea major difficult task in WSN. The attack detection technique is utilized for newlinefinding the attacks and increases the security of data transmission. It gives the newlinesolution to ignore the network attacks and thus achieves secure newlinecommunication. Recently, most of the works designed to carry out secure data newlinecommunication in WSN. But, the detection attack with higher accuracy was newlinenot achieved. To provide better attack detection and secure data newlinecommunication, three efficient methods be developed as follows. newlineStochastic Conditional Maximized Softboost Clustering-based newlineGoldwasser Micali Certificateless Signcryption (SCMSC-GMCS) technique newlineis designed for black hole attack detection and secure data transmission in newlineWSN. SCMSC-GMCS comprises node clustering and certificate signcryption newlineprocesses. At first, stochastic conditional maximized soft boost clustering is newlineapplied to group the nodes based on their energy and trust value. Then the newlineGoldwasser Micali certificateless signcryption is employed for achieving newlinesecure data communication. The designed certificateless signcryption newlinecomprises key generation, encryption, and decryption to improve the data newlinedelivery ratio with lesser delay and routing overhead. newline newline
