Secure Network Coding Approach with Distributed Reprogramming Protocol for Cluster Based Ad-hoc Networks in Dynamic Key Management of Wireless Sensor Networks

Abstract: network coding provide set of secure protocols that rely on simple network coding operations to provide a robust and low-complexity solution for sharing secret keys among sensor nodes, including pairwise keys, cluster keys, key revocation, and mobile node authentication. We consider the problem of secret key distribution in a sensor network with multiple scattered sensor nodes. Our results include performance evaluation in terms of security metrics and a detailed analysis of resource utilization. For security reasons, every code update must be authenticated to prevent an adversary from installing malicious code in the network. All existing reprogramming protocols are based on the centralized approach in which only the base station has the authority to initiate reprogramming. it is desirable and sometimes necessary for multiple authorized network users to simultaneously and directly reprogram sensor nodes without involving the base station, which is referred to as distributed reprogramming. In this case, the network owner can also assign different reprogramming privileges to different users. Motivated by this consideration, we develop a secure and distributed reprogramming protocol named SDRP, The protocol uses identity-based cryptography to secure the reprogramming and to reduce the communication and storage requirements of each node. we address key management in cluster-based mobile ad hoc networks (MANETs). Ensuring secure communication in an ad hoc network is extremely challenging because of the dynamic nature of the network and the lack of centralized management. This scheme is implemented via a combination of ID-based multiple secrets and threshold cryptography. It eliminates the need for certificate-based authenticated publickey distribution and provides an efficient mechanism for key update and key revocation schemes, which leads to more suitable, economic, adaptable, scalable, and autonomous key management for mobile ad hoc networks. Many schemes, referred to as static schemes, have adopted the principle of key predistribution with the underlying assumption of a relatively static short-lived network. An emerging class of schemes, dynamic key management schemes, assumes long-lived networks with more frequent addition of new nodes, thus requiring network rekeying for sustained security and survivability. The theoretical analysyes demonstrates the security properties of the protocol, but we also implement it in a network of resource limited sensor nodes to show its high efficiency in wireless sensor networks.
