Implementing RC5 Encrtption Algorithm On a Web Based Medical Cosultation System

Even though security requirements in medical care are traditionally high, most computerized medical care applications lack sophisticated security measures or focus only on single security objectives. This project is a web
based application for medical consultation system, it describes a special security way to process a medical care data which transporting through a public networks such as the Internet. It proposes a cryptography approach using RC5 as fast and strong block cipher encryption algorithm. In this application, the patient creates an encryption key to encrypt a medical care consultation inquiries and questions before he send it transit through the transport media to the system database. The doctor is a server side who's the administrator and responsible to decrypt and manage the data. This study is to deliver the approach of confidentiality, integrity and trust to the patient's medical data.
