    Student thesis: Doctoral ThesisDoctor of Philosophy


    With the wide spread of mobile phones, PDAs, and Smartphones, M-Commerce has become a major application domain for mobile devices, unlike conventional wired networks, mobile devices allow the user to conduct online transactions regardless of the time and the place as long as there is mobile network coverage. However, online transactions require adequate level of security to insure the confidentiality, the integrity, and the availability of the user’s information. Security measures consume a considerable amount of energy and require more time in processing.

    The aim of this thesis is to optimise the energy and the resources consumption of mobile phones when applying variant symmetric and asymmetric schemes. This aim can be achieved through
    developing A System State Security Management Framework, SSSM, which will implement encryption schemes, symmetric and asymmetric, and will provide different options to enable the
    user to choose the type of encryption, the key size, and number of rounds of computation to optimise the energy consumption level of the mobile phone. This thesis compares the power and the resources consumed by the most commonly used encryption algorithms such as CAST, IDEA, Triple-DES, RSA, and AlGamal. This comparison helps to draw the advantages and disadvantages of each algorithm scheme used in reference to the security level it provides and the power it consumes.

    Implementing this mechanism will enhance the performance of mobile phones by increasing the security levels provided by the encryption schemes and utilising the limited power and resources
    efficiency. Therefore, confidentiality will be presented in mobile phones and variant encryption schemes, symmetric and asymmetric, and changeable key sizes and rounds, will ensure the
    authenticity of both senders and recipients depending on their needs as well as resources available. This research makes contributions in two major areas; the first area consists of the
    novel Energy Aware Encryption polices generated by this work, the second area of contribution is the energy measurements and experimental results which validate the approach presented in
    the research.
