Data Security Solution for Mobile Applications

The paper describes security issues regarding accessing data from a mobile application. There are presented two scenarios regarding device stored information and data access over the network. The paper describes a security architecture based on Rijndael symmetric encryption algorithm that offers a high level of protection for device stored data. The security issues regarding data transfer over network are worked out using a solution based on RSA Asymmetric Algorithm. The architecture is implemented on a Windows Mobile platform using the Mobile Client Software Factory classes
