In symmetric cryptography, TESLA variants are well-known valuable source authentication broadcast scheme that are secure and efficient. But TESLA, versus asymmetric approaches, do not provide confidentiality and immediate authentication, need the synchronization of parties, are not flexible due to synchronization and finally have delayed verification and overflow problem. In this paper, we have proposed...
This paper mainly proposes a new robust and energy-efficient solution for secure operation of wireless sensor networks. It motivates a new paradigm where security is based upon using parameterized frequency hopping and cryptographic keys in a unified framework to provide differential security services for wireless sensor networks.
This paper discusses the problem of achieving bandwidth and energy-efficient neighborhood group key distributions (NGKD) in tactical wireless sensor networks (TWSNs). We present new techniques that improve NGKD performance while also improving the resilience of TWSNs against attacks that combine node capture with message interception. This is accomplished without introducing additional communications...
