Ensuring Data Security and Performance Evaluation in Cloud Computing

Abstract

Cloud computing is threatened by unanswered security issues that are risky for both the cloud providers and users. Cloud is a computing design that manages large sets of distributed resources, of which scientists benefit from their convergence. The aim of this paper is divided into two parts: firstly a brief review on cloud computing mainly focusing on security and secondly offer a solution that eradicates possible threats. In particular, we proposed a new data security model that can efficiently protect the data whether in the cloud database or in transition. We start with an established authentication server and data server providing user authentication, user verification, and data support. The system follows SSL protocol for data encryption and protection, and secure deliver report (SDR) is used for data reliability and integrity of communication.

“…Com essa estratégia é possível aumentar consideravelmente os recursos de infraestrutura da empresa a um custo mais atrativo. Porém, preocupações relacionadas à segurança do ambiente podem impedir que novos clientes utilizem os serviços de uma nuvem (LOMBARDI; PIETRO, 2011) (VAQUERO; MORÁN, 2011) (BREIVOLD et al, 2014) (HASHEM et al, 2015) (SHAMSOLMOALI;ALAM, 2015).…”
