FEATHER A Proposed Lightweight Protocol for Mobile Cloud Computing Security

摘要

Ensuring security for lightweight cryptosystems inmobile cloud computing is challenging. Encryption speed andbattery consumption must be maintained while securing mobiledevices, the server, and the communication channel. This studyproposes a lightweight security protocol called FEATHER whichimplements MICKEY 2.0 to generate keystream in the cloudserver and to perform mobile device decryption and encryption.FEATHER can be used to implement secure parameters andlightweight mechanisms for communication among mobiledevices and between them and a cloud server. FEATHER isfaster than the existing CLOAK protocol and consumes lessbattery power. FEATHER also allows more mobile devices tocommunicate at the same time during very short time periods,maintain security for more applications with minimumcomputation ability. FEATHER meets mobile cloud computingrequirements of speed, identity, and confidentiality assurances,compatibility with mobile devices, and effective communicationbetween cloud servers and mobile devices using an unsafecommunication channel.
