Abstract [en]

The number of mobile devices is increasing rapidly. In a couple of years these handheld devices will continuously be connected to the Internet. Also the popularity of business on the Internet rises as the electronic medium provides several advantages compared to the traditional way. These are only some of the factors that are causing growing concern for security in mobile communication.

Today there are several products for authentication and secure communication over the Internet. However, most algorithms and techniques were designed and optimised for stationary clients such as PCs, which have a high bandwidth network connection and endless power. Handheld devices with less memory, a less powerful CPU, and only narrow bandwidth network connection have more limited possibilities for security than stationary PCs.

The purpose of this M.Sc Thesis was to examine the suitability of the existing techniques for authentication and secure communication for handheld devices in the mobile Internet.

Evaluation of different algorithms shows that the Rijndael algorithm and Elliptic Curves techniques are the most suitable ones for mobile devices. The security protocol I recommend today is SSL.
