In today's digital environment security and privacy of personal information becomes important as an increasing percentage of the population makes daily usage of both mobile devices and cloud storage. Security and assurance of mobile computing is vital to both the normal functioning in people's lives as well as our social, economic and political systems. In this paper we propose and implement a mobile cloud storage system that authenticates users using a gesture based password, and stores private information securely in the cloud using the Amazon Simple Secure Storage Service (Amazon S3). Our solution makes use of the AES and SHA-1 algorithms to protect data, while also making use of SSL to transfer data between the mobile device and the Amazon S3 buckets.

We present the results of an analysis of the usage of our new campus-wide wireless network. A week-long traffic trace was collected in January 2003, recording address and protocol information for every packet sent and received on the wireless network. A centralised authentication log was used to match packets with wireless access points. The trace was analysed to answer questions about where, when, how much, and for what our wireless network is being used. Such information is important in evaluating design principles and planning for future network expansion.
