Abstract

Efforts to protect the confidentiality of data, especially messages on Android smartphones, are by encryption techniques. Some fairly well-known and widely used algorithms still have quite high performance on memory and CPU usage. Meanwhile, Android smartphones have limited resources, so efforts to improve the performance of algorithms on the Android platform need to be done. Various efforts to improve the performance of the Modified AES algorithm have been carried out, such as using Adjusted ShiftRows and Bit-Permutation stages. This study combines the Adjusted ShiftRows and Bit-Permutation stages into the Modified AES algorithm stage and compares the performance of the Modified AES algorithm with the Rijndael, Serpent and Twofish algorithms on 128 bits and 256 bits key lengths. Furthermore determine the most optimal algorithm to be implemented on an Android smartphone. The results showed that the Modified AES algorithm with Adjusted ShiftRows and Bit-Permutation showed increased efficiency and performance due to faster encryption time, reduced memory and CPU usage, therefore this algorithm is feasible to be applied on Android smartphones.
