Abstract: Smartphones' data security has become increasingly important in the advancement of mobile technologies. Users today use smartphones as means of communication, sending and receiving messages, browsing the internet as well as storing sensitive information. Due to these functionalities smartphones today are preferred targets of attacks. Hence, the foremost goal of this work is to provide security for user data on smartphones by the implementation of Blowfish encryption algorithm prior to cloud storage. Blowfish encryption algorithm is a popular and well tested cryptographic algorithm to provide security for user data in mobile cloud computing. Further, there is the need for the development of a mobile application to provide the needed security on smartphones using this existing algorithm. This paper therefore proposed a Secure App using java + xml which was implemented on SoloEncrypt security model. Three Android devices were used to carry out the experiment; Samsung Galaxy On7 Prime, Samsung Galaxy J2 Pro and Samsung Galaxy J7 Nxt. Encryption time and decryption time were parameters used for evaluating the encryption algorithm which are among the standardized metrics approved by the National Institute of Standards and Technology (NIST). The experimental results revealed that the algorithm encrypts with better speed and it takes less time to decrypt when compared with related work.

Abstract: Being fueled by electric power, electric vehicles (EVs) are the sustainable alternatives to the conventional vehicles: EVs are likely to alleviate the environmental pollution brought out by excessive use of fossil fuels. To realize electric locomotion, there should be efficient charging facility in our electrical infrastructure to charge the batteries of the EVs. This work proposes an effective topology that focuses to reduce the stress on the grid due to overlapping of EV load profile with the normal Grid-electricity load profile in technically as well as financially feasible way. The EV’s owner can charge his/her vehicle up to desired SOC level from the charging station with sources: PV, BESS and Grid. Here, BESS is a massive energy storage system that can store energy from the grid as well as from the PV system which supplies power to the load during day-time. BESS supplies the load during the peak of the system and helps the grid relieve as well as reduce the Grid-electricity bills during peak hours. Regulation of EV load sharing and prevention of mismatch between circulating currents supplied by power sources is implemented using fixed droop method. The trend of power demand of EVs throughout a day in a charging station is assumed in accordance with the other related works. The economic feasibility of the proposed system is verified in terms of the payback period of the investment made on the PV and BESS. The simulations are successfully implemented to validate the effectiveness of the system and to demonstrate the load management.
