Abstract: Cloud computing is one of the hottest technology of the IT trade for business. Cloud computing security has changed into a popular topic in sector and academic research. Cloud Computing is a conceptual service based technology which is used by many companies widely these days. ECC algorithm provides secure communication integrity and authentication, along with non_repudiation of communication and data confidentiality. ECC is known as a public key encryption technique based of Elliptical Curve theory that can be used to create speedy, tiny and more efficient cryptography key. It has three protection points: authentication, key generation and encryption of data. This paper will create cloud security and data security of cloud in cloud computing by creating digital signature and encryption with elliptical curve cryptography.
Keywords: Cloud computing, Data security, Cloud security, Encryption, Decryption, Elliptical Curve Cryptography, Digital signature.
