Elliptic Curve Cryptography in Sensor Networks with Hidden Generator Point for Speedup Scalar Multiplication

In Network Security, Cryptography mechanism is used to secure communication with the help of various kind of algorithms provides applicability and suitability for constraint environment such as mobile sensor applications. Here both computing resources and power availability are limiting factors. Thus, it is expecting to have cryptographic algorithms for low power consuming, less computing, and highly secure for mobile sensor networks. Elliptic curve cryptography (ECC) is an emerging favorite because requires less computational power, communication bandwidth, and memory when compared to other cryptosystems. In this paper we present our new design, a hidden generator point, which offers an improvement in protection from the man-in- middle attack which is a major vulnerability for the sensor networks. Even though there are other ways to implement hidden generator point.
