Executive Summary:
Patton Fuller community hospital uses the clinical system, which is an integrated suite of healthcare applications that support various patient care like registration and scheduling; clinical orders, chart entries and reviews for physicians, nurses, emergency department personnel, and other care providers; systems for lab technicians, pharmacists, and radiologists; billing systems and insurers; and outpatient systems for the hospital’s outpatient clinics.System is built on a two-tier, client-server architecture, where the client is responsible for the presentation logic and application logic, and the server responsible for the data access logic and data storage. It allows multiple users across the network to share the server’s resources. Since the Hospital has to follow HIPPA compliance and regulation law, Patton-Fuller Community Hospital will need to make sure encryption rules are applied to their system and data is protected. Below is the symmetric and asymmetric encryption method to be used. 1) Public Key 2) Private Key 3) IPsec

Public Key (Asymmetric): This encryption method will give pair of keys Message is encrypted using the public key and can only be decrypted by private key. Example RSA, Advanced Encryption Standard (AES) * RSA – It is a public key encryption method * It is a standard encryption method especially used for transmitting data over internet. * It is cost effective solution with hardware based encryption method.
Private Key (Symmetric): This key is created as Private and used during the decryption .Example Advanced Encryption standard (AES).

* Mainly used for modem, routers * It is cost effective and also secured.

IPsec: It is used for secure data package at IP layer .It supports two encryption mode * .It is widely used for virtual private network.
