Development of Design for Enhancing Trust in Cloud’s SPI Stack

Abstract

Cloud computing defines the SPI model, which is generally agreed upon as providing Software-as-a-Service, Platform-as-a-Service and Infrastructure-as-a-Service. Interest in those service delivery models is growing because the paradigm offers to cloud customers high computational resource on-demand with a low cost. However, trustiness in the cloud services regarding the security and the privacy of the delivered data is the most critical issue in the SPI model. In this paper we propose a trusted SPI model that gives cloud customer more confidence into SPI services by leveraging a trust in a neutral SPI certifying authority. The proposed model prevents insider attacks from tampering with application service before and after the computational resource was launched and allow cloud customer to verify if its node run in a secure environment
