Abstract

Proportional to the growth in the usage of Human Sensor Networks (HSN), the volume of the data exchange between Sensor devices is increasing at a rapid pace. In this paper, we have proposed an Energy Efficient Lightweight Encryption (EELWE) algorithm for providing the confidentiality of data at the sensor level, particularly suitable for resource-constrained environments. Results obtained have proved that an EELWE consumes less energy relative to present lightweight ciphers and it supports multiple block sizes of 32-bit, 48-bit, and 64-bit.
