Application of Elliptical Curve Cryptography in Empowering Cloud Data Security

Cloud computing is one of the most preferable and used technologies in IT Industry in the present scenario. Providing security to cloud data in cloud environment has become popular feature in industry and academic research. Cloud Computing is a conceptual concept based on technology that is widely used by many companies these days. The Elliptical Curve Cryptography algorithm ensures the integrity and authentication of secure communications with non-repudiation of communication and data confidentiality. Elliptical Curve Cryptography is also known as a public key cryptography technique based on the elliptic curve theory that can be used to create a fast, small, more efficient and unpredictable cryptographic key. This paper provides authentication and confidentiality to cloud data using Elliptical Curve Cryptography. This paper attempts to evolve cloud security and cloud data security by creating digital signatures and encryption with elliptical curve cryptography. The proposed method is an attempt to provide security to encryption keys using access control list, wherein it lists all the authorized users to give access to the encryption keys stored in cloud
