Computer entertainment is a big business today. Due to the availability of broadband network connections, the Internet is already a platform for many high quality multimedia applications. For example, online theaters and multi-player online games (MOG) are two of the most popular multimedia applications on the Internet. Although the Internet provides us a very convenient channel for data dissemination, its open architecture leads to many security issues. The security problems are especially complicated for computer entertainment applications since we must address both efficiency and security at the same time. In this thesis, we tackle four security issues in different aspects of computer entertainment applications. Specifically, the issues are (1) "to provide secure multimedia streaming while allowing proxy caching by untrusted third parties", (2) "to detect cheating in MOGs other than using conventional labor-intensive methods", (3) "to synchronize game clients in highly-interactive MOGs while resisting cheating in both the application and protocol level", and (4) "to exchange messages in peer-to-peer (P2P) MOGs so that distributed simulation is allowed but information exposure is mitigated". For each of the above issues, we present an effective solution that preserves the architecture of that particular multimedia application and also is feasible and efficient to deploy on the Internet. / Yeung, Siu Fung. / Adviser: John C.
