摘要：The rapid development of distributed system technologies enforces numerous challenges. For example, one of the most critical challenges facing cloud computing is ensuring the security of confidential data during both transfer and storage. Indeed, many techniques are used to enhance data security on cloud computing storage environment. Nevertheless, the most significant method for data protection is encryption. Thus, it has become an interesting topic of research and different encryption algorithms have been put forward in the last few years in order to provide data security, integrity, and authorized access. However, they still have some limitations. In this paper, we will study the security concept in Cloud Computing applications. Then, an ECC (Elliptical Curve Cryptography) based algorithm is designed and tested to ensure cloud security. The experimental results demonstrate the efficiency of the proposed algorithm which presents a strong security level and reduced execution time compared to widely used existing techniques.
