Analysis of the Impact of Homomorphic Algorithm on Offloading of Mobile Application Tasks.

Mobile accounts for almost half of the web traffic worldwide. However, these devices still have computational and energy limitations. The offloading technique attacks these problems when expanding the mobile device's capabilities to a remote environment, preserving local resources, and enriching the user experience. However, during this procedure, data could be transmitted through the network without protection, which is unfeasible for applications that manipulate confidential data. This paper evaluates the performance of computational offloading when adopting homomorphic encryption during data migration. Our results showed that the time spent in the offloading increased to 984 times when performed through this type of encryption.
