Abstract

WSN’s are generally deployed for collecting data from unattended or hostile environment. Several application specific sensor network cryptography algorithms have been proposed in research. however wsn’s has many constrictions, including low computation capability, less memory, limited energy resourses, vulnerability to physical capture ,which enforce unique security challenges needs to make a lot of improvements. In this paper presents a novel cryptography algorithm for wireless sensor network security, which presents a generic transformation from weak secure symmetric and asymmetric scheme to a hybrid encryption scheme. A revised Feige-Fiat-Shamir ZKP scheme for the Wireless sensor Networks (WSNs) that reduces the execution dynamics in the scheme and increases the trust of the Verifier and prover, and makes the authentication process faster and more efficient.
