Abstract:

Data security continues to be one of the most leading and predominant concerns encountered in cloud computing and that can be a strong barrier for organizations to its adoption. To ensure privacy and confidentiality of the sensitive data, various techniques have been proposed in order to mitigate risks pertaining to cloud security. The encryption solution of outsourced data before sending to the cloud provider has been the most widely used mechanism to bridge this security gap. In this paper, we propose an effective security model to enhance data security in the cloud environment using the fully homomorphic encryption which allows performing operations on encrypted data without compromising the encryption. This framework is based on Encryption as a Service (EaaS) including the private cloud OpenStack platform. In addition, our proposed architecture implements the public key infrastructure cryptography (PKI) scheme to secure data transmission over the network.
