Estudo comparativo do impacto da segurança em ambientes de mobile cloud computing

Abstract

The evolution of the internet, mobile devices and applications have brought new needs to the people, such as being always connected, whether for communication, stay informed or even for personal entertainment with the use of applications. But even with all the advancements, mobile devices remain resource-constrained, and modern applications are increasingly demanding these features to deliver better user experiences. To mitigate this problem, Mobile Cloud Computing uses Cloud Computing to "expand"the capabilities of mobile devices through offloading, where offloading concerns data migration and / or mobile device processing for a remote environment (Cloud). However, this process has security problems, as data can be migrated over the network without any protection. To work around this problem there are solutions using encryption techniques to ensure data security. This work aims to conduct an analytical study on the impacts on mobile application performance by using encryption in offloading using the processing time metric. The main result is that the larger the request object for offloading, the greater the time spent on communication and consequently the total time in the whole process and that depending on the cryptographic algorithm, its influence is insignificant. for the process as a whole.
