A Survey: Security in Patient Data Communication using Cryptographic Algorithm

Abstract: Wireless medical sensor networks are more vulnerable to many more attacks than the wired networks. Mobile Ad-Hoc Networks (MANETs) are particularly useful and well-suited for critical scenarios, including healthcare applications, home patient monitoring, military. MANET has number of routing protocols Ad hoc On-Demand Distance Vector (AODV) routing protocol is one of them which is the most suitable protocol for healthcare application purpose. In this project we are considering as a base protocol. Here the practical approach to prevent the inside attacks in the healthcare applications from attackers. We provide the security to the network layer by using encryption and decryption standards and a cryptographic mechanisms such as Advance Encryption Standard (AES), Rivest-Shamir-Adleman Algorithm (RSA) and Secure Hash Algorithm (SHA). Network Simulator Software (NS2) has used for the simulation purpose.

Keywords: Ad-hoc on-Demand Distance Vector, AES, RSA, SHA.
