Abstract :Ensuring energy efficiency, data reliability, and security is important in wireless sensor networks insert ignore into journalissuearticles values(WSNs);. A combination of variants from the cryptographic secret sharing technique and the disjoint multipath routing scheme is an effective strategy to address these requirements. Although Shamir`s secret sharing insert ignore into journalissuearticles values(SSS); provides the desired reliability and information-theoretic security, it is not energy efficient. Alternatively, Shamir`s ramp secret sharing insert ignore into journalissuearticles values(SRSS); provides energy efficiency and data reliability, but is only computationally secure. We argue that both these approaches may suffer from a compromised node insert ignore into journalissuearticles values(CN); attack when a minimum number of nodes is compromised. Hence, we propose a new scheme that is energy efficient, provides data reliability, and is secure against CN attacks. The core idea of our scheme is to combine SRSS and a round-reduced AES cipher, which we call `split hop AES insert ignore into journalissuearticles values(SHAES);`. Both the simulation results and the theoretical analysis are employed to validate the near-sink CN attack, and a secure reliable scheme using SHAES is proposed.
