Secure access schemes in mobile database systems

Mobile computing is a newly emerging computing paradigm. Whether using the term mobile database system or some other form, the database concept is essential to the mobile computing environment. This work employs a more thorough yet general means of defining the mobile database system, along with several application scenarios. Possible secure access schemes are also presented for databases in a mobile computing environment. The tradeoffs of these schemes are also analyzed. Moreover, the feasibility of applying some possible secure access methods is explored, along with the potential difficulties and unresolved issues. Finally, concluding remarks and recommendations for future works are made.
