ABSTRAK
Pengkomputeran awan mudah alih menawarkan banyak kelebihan bagi organisasi dan pengguna kerana ketersediaan perkhidmatan pada bila-bila masa dan dari mana saja, pengurangkan kos pengedaran sistem maklumat yang diedarkan, dan menjimatkan usaha dan masa yang diperlukan oleh pengguna untuk mendapatkan perkhidmatan.
Keselamatan perkhidmatan pengkomputeran awan mudah alih merupakancabaran utama yang dihadapi oleh pengamal dan pengguna perkhidmatan mi. Matlamat utama penyelidikan ini adalah untuk mencadangkan model pengkomputeran awan mudah alih yang selamat berdasarkan pendekatan pembangunan hibrid bagi pihak universiti meningkatkan keberkesanan perkhidmatan yang disediakan olehnya dan memastikan tahap keselamatan pengkomputeran awan mudah alihnya berkesan. Untuk mencapaimatlamat ini, tiga objektif penyelidikan telah ditetapkan iaitu (1) untuk mengenal pasti kaedah dan proses keselamatan yang paling berkesan untuk meningkatkan prestasi keselarnatan pengkomputeran awan mudah alih, (2) untuk mengkaji kepentingan dan cabaran yang dihadapi olehkeselamatan pengkomputeran awan mudah alih di persekitaran universiti, dan (3) mengkaji pemboleh ubah berkaitan, komponen, dan kaedah keselamatan yang diperlukan untuk membina model yang dicadangkan. Kajian literatur telah dijalankan untuk mencapai objektif penyelidikan pertama. Satu kaji selidik telah dijalankan dengan 38 orang pelajar dari Universiti USIM bagi mencapai objektif penyelidikan kedua. Satu temu bual dengan tiga orang pakar dalam bidang keselamatan sistem maklumat telah dijalankan untuk menangani objektif penyelidikan ketiga. Penemuan pengesahan menunjukkan bahawa struktur, kaedah keselamatan yang dicadangkan, dan komponen model yang dicadangkan berguna untuk menjamin keselamatan perkhidmatan pengkomputeran awan mudah alih di universiti. Model yang dicadangkan dapat mengisi kekurangan dalam bidang pembangunan keselarnatan model pengkomputeran awan mudah alihbagi perkhidmatan yang disediakan di universiti. Model yang dicadangkan juga boleh menggalakkan pihak universiti menggunakan perkhidmatan pengkomputeran awan mudah alih, dan menggalakkan para pelajar menggunakan perkhidmatan tersebut.

ABSTRACT
Mobile cloud computing offer many advantages for organizations and users such as availability of services in anytime and from anywhere, reduce the costs of distributed
information systems, and save the users efforts and time the required to accomplish the services. The public services security of mobile cloud computing represents the main challenges of adopts and uses these services. The main aim of this research is to propose a secure mobile cloud computing model based on hybrid development approach for universities' in order to enhance the effectiveness of services provided by university and to ensure an effective mobile cloud computing security level. To
address this aim, three main research objectives are formulated; 1) to identify the most applicable security methods and processes to increase the security performance of mobile cloud computing, (2) to study the important and challenges that face the security of mobile cloud computing according to university environment, and (3) to study the related variables, components, and security methods that needed to construct the proposed model. The literature review was conducted to address the first research
objective. A questionnaire survey with 38 students from USIM University was conducted to address the second research objective. An interview with three experts in infonnation system security was conducted to address the third research objective.
The validation findings show that the structure, the proposed security methods, and the components of the proposed model are useful to secure the mobile cloud computing services in the university. The proposed model fill important research gap which is the lack of the development of security cloud computing model for university services. The proposed model could encourage the university to adopt the mobile cloud computing services, and encourages the students to use these services.
