This paper presents results on modelling of AES and RSA encryption algorithms in terms of CPU execution time, considering different modelling techniques such as linear, quadratic, cubic, and exponential mathematical models, each with the application of piecewise approximations. C#.net framework is used to implement this study. The authors consider the symmetric encryption algorithm named AES and the asymmetric encryption algorithm named RSA to carry out this study. This study recommends quadratic piecewise approximation modelling as the most optimized model for modelling the CPU execution time of AES and RSA towards encryption of data files. The model proposed in this study can be extended to other symmetric and asymmetric encryption algorithms, besides taking them over a mobile cloud environment.

Aes Encryption Algorithm

Mobile cloud computing provides an opportunity to restrict the usage of huge hardware infrastructure and to provide access to data, applications, and computational power from every place and in any time with the use of a mobile device. Furthermore, MCC offers a number of possibilities but additionally creates several challenges and issues that need to be addressed as well. Through this work, the authors try to define the most important issues and challenges in the field of MCC technology by illustrating the most significant works related to MCC during recent years. Regarding the huge benefits offered by the MCC technology, the authors try to achieve a more safe and trusted environment for MCC users in order to operate the functions and transfer, edit, and manage data and applications, proposing a new method based on the existing AES encryption algorithm, which is, according to the study, the most relevant encryption algorithm to a cloud environment. Concluding, the authors suggest as a future plan to focus on finding new ways to achieve a better integration MCC with other technologies.

As the daughter of modern wireless communication technology & computer network technology, Wireless Local Area Network(WLAN) is being used widely in many areas. It is well known that WLAN has the advantages such as simple network configuration, high transmission rate, good extensibility and mobility, and convenience to carry, etc. However, its security mechanism is not perfect to guarantee its security because of some design flaws in safety precautions. The application of AES in WLAN improves its data confidentiality. The work presented in this paper focuses on present AES encryption algorithm security problem and optimization of its S Box. The improved algorithm this paper put forward in WLAN, is proved to be efficient.
