Data Security and Privacy Protection with Cryptography in Cloud Computing

Abstract

It is well known that cloud computing has Many potential advantages and it plays a vital role in Present day to day life. It helps users to maintain their data over the internet by widening its wings in all fields to deliver services. Data security has consistently been a major issue in information technology. Cloud computing has several customers such as ordinary users, and enterprises who have different motivation to move to cloud. In cloud computing environment, data security becomes particularly serious because the data is located in different places even in the entire globe. In cloud architecture, Data security and privacy protection Issues are relevant to both hardware and software. When the Issues of cloud security come up, security threats such as maintenance of data integrity, data safety and data hiding dominate clients concerns. The data communication on the internet or over any network is at risk to the attackers attack. So, in order to secure the data some encryption scheme is used. This paper serve a concise analysis on data security and privacy protection and its issues associated with cloud computing. Then this paper provides cryptographic techniques, Elliptic Curve Cryptography for data encryption/Decryption was used along with Diffie Hellman based on Elliptic Curve mechanism for connection establishment.
Keywords: Cloud Computing, Data security, Privacy Protection, Elliptic curves cryptography.
