Securty Enhancement USING RSA Algorithm for Emergency Situation Detection System

Abstract
Falls represent a critical threat to the health and independence of frail and elderly. This paper proposes a secure data transmission using RSA algorithm (Rivest Shamir Adleman Algorithm)to transfer the data collected during emergency situation from frail and elderly with the help of Ambient Assisted Living (AAL). Ambient Assisted Living (AAL) is a novel concept which helps an individual to empower the day today living as well as workplace and to remain active for longer with the use of information and communication technology (ICT). Cryptography plays an enormous role in our highly technological daily life, and we are significantly relying upon the study of hiding information in plain sight. Typical wearable devices utilize a dedicated mobile phone as relay-node move the gathered sensor information to a server. The proposed fundamental key arrangement and authentication scheme guarantees anonymity and untraced ability for both sensors (wearable device) and mobile relay nodes, and relies on symmetric key-based operations to work under resource-constrained conditions. Bluetooth Low Energy (BLE) communication technology is utilized to connect sensor nodes (wearable devices) and mobile relay. This paper focuses on the code implementation and the encryption and decryption procedure using RSA algorithm is provided in detail. Encryption gives strong security to the information.
