Wireless sensor networks (WSN) are constrained in terms of computational and energy resources. There is enormous research going on for converting the stream based cipher to public key based cipher to increase the level of security in the information transfer in WSN. A recent research validates public key cryptography such as Elliptic Curve Cryptography (ECC) is feasible for wireless sensor network. Also symmetric key algorithms are efficiently implemented and used in wireless sensor network. This paper presents a Dynamically Secured Authenticated and Aggregation scheme (DSAA) by combining the public and symmetric key cryptography leads to increase in security, computational speed as well as reduces memory usage. It also incorporates data aggregation which reduces the in-network processing and increases the nodes lifetime. The simulation processes of this proposed hybrid cryptography named DSAA is used to authenticate a person in an indoor environment.
