Abstract:
Short Message Service (SMS) is a text messaging service component
of mobile communication systems. It uses standardized communications protocols to exchange short text between mobile devices. SMS does not have any
built-in procedure to offer security for the text transmitted as data. Most of the
applications for mobile devices are designed and developed without taking
security into consideration. In practical use, SMS messages are not encrypted by
default during transmission. Therefore, a data confidentiality approach to SMS
on Android will be developed in the paper. It includes design, implementation
and confidentiality measurement of RC4 stream cipher for SMS data confidentiality on mobile networks.
