Abstract:
In this paper, a security solution for data storage in cloud computing is examined. The solution encompasses confidentiality and integrity of the stored data, as well as a secured data sharing mechanism in the cloud storage systems. For this purpose, cryptographic access control is used, which is mainly based on cryptography. Based on an analysis of the cryptographic access control mechanism, a design of encryption algorithm is created for a system, which is intended to demonstrate the security mechanism in practice. Finally, on the basis of the proposed design of encryption algorithm which is created, a prototype is implemented. Data confidentiality and integrity are ensured by data encryption. For encryption of data, symmetric cryptography is used. The main quality of the system is that all cryptographic operations are performed on the client side, which gives users more control on the security of their data, and thus the data are not dependent on the security solutions provided by the servers.
