Peer-to-Peer Security Implementation Between Mobile Phones
Stefan Eskelid () och Fredrik Larsson ()
It is a well known fact that the security of transmitted data on the GSM system is not sufficient.
The radio channel is encrypted by the weak A5 cipher, and communication between base stations is not
encrypted at all.
For some organizations, secure communication between their mobile units is of outmost importance. Hence,
they buy specially designed phones, where end-to-end encryption is implemented in hardware. Such phones are
of course expensive.
Modern mobile phones allow applications to be downloaded and executed on the phone. So it would be possible to implement
end-to-end encryption in software and then put it as an application on the phone.
Your task is to broaden the ideas above a little by implementing a security kit (secure conversation, secure email, secure SMS/MMS, ...)
that has end-to-end protection. The security kit should protect the communication between two Sony Ericsson P900 mobile phones.
In also includes constructing a PKI with certificates for the phones/users inside an organization. It should result in a complete solution
for a organization requiring end-to-end security between their mobile units.
The department has bought a Codewarrior Wireless Development Kit for the Symbian OS (used on the P900 phones), which will be used
for development. The implementation is done in C/C++.
The project will take place at the Dept. of Information Technology and is suitable for 2 students.
