Cloud computing has been envisioned as the de-facto solution to the rising storage costs of IT Enterprises. With the high costs of data storage devices as well as the rapid rate at which data is being generated it proves costly for enterprises or individual users to frequently update their hardware. Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance. Cloud storage moves the user’s data to large data centres, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many new security challenges which need to be clearly understood and resolved. One of the important concerns that need to be addressed is to assure the customer of the integrity i.e. correctness of his data in the cloud. As the data is physically not accessible to the user the cloud should provide a way for the user to check if the integrity of his data is maintained or is compromised. In this paper we provide a scheme which gives a proof of data integrity in the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the customer and can be incorporated in the Service level agreement (SLA). This scheme ensures that the storage at the client side is minimal which will be beneficial for thin clients.

Abstract: Cloud computing has been envisioned as the de-facto solution to the rising storage costs of IT Enterprises. With the high costs of data
storage devices as well as the rapid rate at which data is being generated it proves costly for enterprises or individual users to frequently update their
hardware. Apart from reduction in storage costs data outsourcing to the cloud also helps in reducing the maintenance. Cloud storage moves the user’s
data to large data centres, which are remotely located, on which user does not have any control. However, this unique feature of the cloud poses many
new security challenges which need to be clearly understood and resolved. One of the important concerns that need to be addressed is to assure the
customer of the integrity i.e. correctness of his data in the cloud. As the data is physically not accessible to the user the cloud should provide a way for
the user to check if the integrity of his data is maintained or is compromised. In this paper we provide a scheme which gives a proof of data integrity in
the cloud which the customer can employ to check the correctness of his data in the cloud. This proof can be agreed upon by both the cloud and the
customer and can be incorporated in the Service level agreement (SLA). This scheme ensures that the storage at the client side is minimal which will be
beneficial for thin clients.

Abstract: This paper presents a unified multilevel converter of switched reluctance motors (SRMs) served by an aided front-end circuit for plug-in
hybrid electric vehicle (PHEV) applications. Various operating modes shall be obtained by changing the on-off conditions of the switches in the front-
end circuit. In generator mode, the battery bank is connected to raise the phase voltage for quick excitation and demagnetization. In battery driving
mode, the converter is redesigned as a four-level converter, and the capacitor is used as an extra charge capacitor to produce multilevel voltage outputs,
which improves the torque competence. The operating modes of the proposed drive are elucidated and the phase current and voltage are examined in
details. The battery charging is logically attained by the demagnetization current in motoring mode and by the regenerative current in braking mode.
Also, the battery shall be charged by the external power source through the proposed converter when the vehicle is in halt condition. The SRM fed PHEV
can operate at variable speeds by organising the power flow between the generator and battery. Simulation in MATLAB/Simulink and analysis on a
three-phase SRM confirm the usefulness of the proposed converter topology.
