Design and implementation of Energy Efficient Lightweight Encryption (EELWE) algorithm for medical applications

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.
