Remote sensing infrastructures are now in widespread use to acquire detected information. Since the deployed nodes are separated, they need to cooperatively communicate sensed data to the base station, as shown in Fig.1. Additionally, the carried information probably contains confidential data. However, the properties of wireless communications are vulnerable to an exposed environment. Hence, secure data transmissions for cooperative information integration in sensor networks are essential. In general, wireless sensor nodes have limited resources, and they cannot provide sufficient CPU, memory and bandwidth to address complex operations. The proposed scheme depends on Discrete Logarithm Problem (DLP) of Elliptic Curve Cryptography (ECC), and exploits a smaller key size to achieve comparable security levels than Rivest Shamir Adleman (RSA) and Diffie-Hellman (DH) cryptosystems. Consequently, this paper exploits Elliptic Curve Diffie-Hellman (ECDH) based security methods to achieve cooperative secure information integration.
