- Wireless Body Area Network (WBAN) is an emerging technology used in health care scope, it consists of a number of intelligent sensors that collect the medical data from human body and transfer it by WLAN to the personal device that in turn transfer the patient data to the medical server via the internet where a professional analyzes this data. The back-end server contains sensitive and critical data, and thus it must be enjoyed with high security and privacy. If the patient data could be stolen, tampered, or accessed by any unauthorized person, the data can be lost and even worst altered. In this thesis, a Distributed Storage System (DSS) is used to provide security and privacy to the patient information through distributing the storage among many trusted servers spared in the network instead of storing in central server. The DSS uses erasure codes for this purpose. The implemented system consists of one Primary Server (PS) that has the main database, two Storage Servers (SS) responsible for storing patient data, and one Reader Server (RS) that collects patient information from SSs to read it. The PS encrypts the data using Redundant Residue Number System (RRNS) technique that is depending on a library of moduli in the encrypting process to generate residues. Three algorithms have been implemented to decode RRNS: Chinese Remainder Theorem (CRT), base extension (BEX) with mixed radix conversion, and New Chinese Remainder Theorems (CRT I). RSA has been used to encrypt any exchange messages between servers, and DSA has been used for signing the residues and File Descriptor (FDs) before sending process. After implementing of the system, simulation results have shown that whenever the size of moduli is large, the time of the encoding and decoding process and the size of the sent message will be small and the code efficiency is high. CRT I has considered to be the best for decoding RRNS because it makes the computations faster and functional with low overheads. The security of the system has been ensured where RRNS provide confidentiality and dependability services for the patient data, in addition to using DSA for ensuring integrity and RSA for archiving confidentiality, authentication, and non-repudiation.
