ABSTRACT
Software crash is inevitable and the most common type of software failures. This type of failures is characterized in software testing, reliability, and quality assurance, but not in the cyber security. We have studied the software crash behaviors by constructing symbolic failure models, and automatically produce software attacks through the manipulation of the symbolic model. This work has revealed a severe cyber security threats against software quality. That is, software crash failures introduced by bugs are able to be automatically exploited. If bugs are exploited and attacked, arbitrary code can be executed and a backdoor channel will be built.
That is the concept and talk title of Bugs as a Backdoor.
If a backdoor channel is built by embedding bugs in the system, former research on Trojan horse identification will be reduced to the finding of software bugs, still an intractable problem in software engineering, and programming languages.
In this talk, we will introduce the development of exploitable crash detection and the process of automatic exploits (attack input) generation. The generation process has been improved and 7,000 times faster than our initial attempt. If attacks are generated by tools from software crashes, Bugs as a Backdoor is feasible without writing an explicit Trojan horse in the system.
A programmer or the software vendor can leave bugs in the system, as unintended features and deniable trapdoors.

ABSTRACT
Recently, there have been a number of studies applying game-based learning supported by technology into English language learning. Claims have been made that games could increase students’ learning motivation, which is the key to succeed in learning a foreign language. With its main feature of online interactions with the gaming system and the avatars of other players, enabling collaborative exchanges of thoughts, emotions, and ideas among the game players, massively multiplayer online role-playing games (MMORPGs) have been applied into
educational environments, particularly in English language learning.
Learner characteristics and cognitive learning outcomes have been identified as the key factors in research on the implementation of games in educational settings. Although previous studies have examined the potential of applying MMORPGs into educational settings, a small number of in-depth studies, investigating the relationship between prior ability and learner cognitive learning outcomes, are reported in the literature regarding English language learning.
This talk presents a virtual learning environment by utilizing an MMORPG-based instruction in an English lesson. It was to examine how the learners’ prior ability, naming different levels of online gaming experience, affected learners’ cognitive learning outcomes. The purpose of this study was to investigate the learning effectiveness of knowledge acquisition after playing the proposed game and to discover whether there are significant differences in the effectiveness of learning with the game between experienced learners and inexperienced learners with regard to online gaming experience.
