Abstract:
Recently, wireless sensor networks (WSNs) have been established for vast diversity of applications such as military tracking, health care monitoring, traffic monitor-ing, where sensor nodes are frequently move from different locations. Secure data transmission in wireless sensor network is challenging task. A good encryption key management protocol is required to secure data and communication. Clustering is a novel approach and practical way out to increase the system performance of WSNs. Proposed system presents a effective key management to secure data transmission for WSNs, in which the clusters are designed. Proposed work present two secure and efficient data transmission protocols for WSNs, called IBS and IBOOS, by using the identity-based digital signature (IBS) technique and the identity-based online/offline digital signature (IBOOS) scheme, respectively.In IBS, network security depends on the use of the Diffie-Hellman problem in the pairing domain. SEDT-IBOOS re- duces the computational overhead for protocol security, which is important for WSNs, while its security depends on the wireless network design. Proposed system show the feasibility of the effective key management with SEDT-IBS and SEDT-IBOOS pro- tocols with use of security requirements and security analysis against various attacks such as passive attack, known key attack and impersion attack.We have discussed a novel integrated approach of IBS and IBOOS for effective key management. We have provided experimental evaluation of the proposed protocol through simulation results.
