Data Security in M-Learning Messaging Services
The m-learning field has been defined new educational services that deliver knowledge and content on mobile devices, highlighting a dreamed educational concept, anywhere, anytime. Education processes have evolved in the last decades by integrating new technology. Many m-learning services use SMS to deliver simple text content because it has a low cost, it is available on all mobile devices and has wide coverage and availability. As more and more sensitive data is processed by m-learning services, the authors propose a solution that will secure the SMS content and that will have minimal impact on the device performance. The solution implements a symmetric encryption scheme based on AES and is used by a distributed m-learning architecture. The paper presents two examples developed for Java ME and .NET CF platforms.
