| dc.description.abstract | The amount of wireless technologies is getting bigger and wider. It is more and more
common in everyday use for a huge amount of the people. A cellular phone is something
that everyone got in addition to normal access the Internet. So, why not both at the same
time. When data is transmitted over the Internet and are communicating with wireless
technologies, there are several vulnerable points. There have to be secure data
communication, and the security is only something that should lay behind which people
do not have to think about. Unfortunately, this is not the way it is, there are different
technologies that cover the security better than others.
This master thesis covers some of the different technologies that is in everyday use.
Where the concentration is on the wireless technologies and how to combine these
securely. The technologies cowered are; Bluetooth, GSM/GPRS, IPSec and WTLS
covered by WAP.
One essential purpose of WAP is to provide a way to bring commercial applications into
mobile terminals. Security mechanisms of GSM or GPRS do not necessarily provide
enough security for all WAP applications. Additional security mechanisms need to be
implemented to the mobile terminals and the network. Mobile terminals unfortunately
usually have limited computing resources, and implementing efficient security
mechanism can be difficult.
Since both WAP enabled GSM/GPRS telephones and Bluetooth devices support the use
of WAP and IP communications, it is nothing that says that WTLS and IPSec could not
been used to secure the communication.
Both, WTLS and IPSec support some kind of end-to-end security. This thesis covers
some of the solutions that may be used together with the wireless technologies
GSM/GPRS and Bluetooth. In the end there are an overview over different combinations
and a suggestion to secure the data communication. | en |
