Secure Access Schemes in Mobile Database Systems

Mobile computing is a newly emerging computing pa radigm. 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 mob ile database system, along with several application scenarios. Possible secure access schemes are also presented for databases in a mobile computing environment. The tr adeoffs of these schemes are also analyzed. Moreover, the feasibilit y of applying some possible secure access methods i s explored, along with the potential difficulties and unresolved issu e . Finally, concluding remarks and recommendations f r future works are made.
