DATA SECURITY MODEL IN CLOUD USING HECC FOR KEYWORD BASED SEARCH

Abstract

Cloud computing is a easiest way to share a data in various users. Nowadays cloud storage become more popular but the user can share any sensitive data to a cloud server should be treated as untrusted entity. Our proposed work is each and every data indexed in keyword should be generated after encrypted file. A key values are stored in index some authorized user wants to identify the data using keyword in cloud to improve the performance time in HECC algorithm. Hence, it is necessary to implement Data Encryption and Decryption scheme with cloud storage to provide automatic encryption/decryption in AWS cloud service. The purpose of using HECC for encryption/decryption is that it is secure and high computational complexity.
