Abstract [en]

The objective of this thesis is to investigate and compare different possible solutions  for  achieving  secure  communications  using  the  mobile  terminals  for  the  next  generation  cellular networks. The trend is that  these  terminals  will  become more  equivalent to today’s Personal Digital Assistants (PDAs) regarding the possibilities of  interaction.

Different  possibilities  for  achieving  secure  communications  exist  today.  Different  security  protocols  works  at  different  layers  in  the  IP-stack.  An  evaluation  of  the  protocols  was  therefore  done  as  a  part  of  the  thesis.  I  have  investigated  how  the  position of the security protocol in the IP-stack affects the applications that are to use  the security protocol.

When using cellular networks, such as the GSM network, the latency in the network  together with the available bandwidth may impose difficulties in using some security  protocols. A high latency, for example, introduces long negotiation and setup times.

To  investigate  the  characteristics  of  using  a  GSM  connection  to  the  Internet,  some  tests have been carried out. The purposes of the tests were to find out how the setup  and negotiation times, and the transfer rates are affected by using a cellular network.

The tests I conducted shows that the latency in the GSM network is high, about one  second. Therefore, protocols that use few but larger messages are better than protocols  that use many small messages.
