Elaboração de Modelo para Proteção de Arquivos em Discos Virtuais usando os Esquemas IBE e ICP

Abstract

The virtual disks have changed the way how the users are sharing the files over Internet, even with limited security capabilities available in these services for data protection assurance. So alternative methods for data security in cloud are needed, like using cryptography. This paper come up with a hybrid cryptography model on such scenario, converging the asymmetric schemas IBE and ICP to implement the data confidentiality and user authentication, respectively. A software coded on Java programing language was developed in order to simulate the security operations, as well as to provide the data used in performance analysis, indicating that the model is a secure option for data protection in cloud with a good user experience.
