SCEHSS: Secured Cloud Based Electronic Health Record Storage System with Re-Encryption at Cloud Service Provider

R. Sumathi, Member, IACSIT and E. Kirubakaran

Abstract—An electronic health record system is a collection of health related information. Instead of collecting data from single health care centre, data could be collected from various health care centers. Collected data could be further effectively utilized by healthcare and research community. Cloud computing paradigm gives better platform for connecting various communities providing data and location independence with less maintenance. A Cloud Electronic Health Record (CEHR) integrates data to serve different needs. The goal is to collect data once and use it multiple times to adopt latest technologies in medical domain. Security for data-in-transit is one of the major issues in cloud as well as in EHR systems. Our concentration is achieving highly secure data transmission through multiple encryption and re-encryption in the cloud environment without trusting cloud service provider cent percent. Using both symmetric and asymmetric algorithms the security levels of encryption is strengthened. In 2008, Libert and Vergnaud presented the first construction of unidirectional proxy re-encryption scheme with chosen-ciphertext security in the standard model. We extended the unidirectional proxy re-encryption scheme to cloud environment by assigning the responsibility of proxy to cloud service provider for securing data-in-transit.

Index Terms—Electronic health record, ciphertext security, cloud computing, cloud service provider, re-encryption.
