1. 1. Lightweight Inlined Reference Monitors for Securing Extensible and Open Systems

   Författare :Phu Phung; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Security; Inlined Reference Monitors; JavaScript; Vehicle Software Security;

   Sammanfattning : This thesis studies an alternative implementation of asecurity reference monitor in the contexts of extensible and opensystems. A security reference monitor is a classic approach to imposing asecurity policy on an otherwise untrusted system by using a trusted componentwhich intercepts security-relevant resource requests and applies a securitypolicy to decide whether to grant such requests.

3. 2. Design and Implementation of Thread-Level Speculation in JavaScript Engines

   Författare :Jan Kasper Martinsen; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallel computation; web applications; thread-level speculation;

   Sammanfattning : Two important trends in computer systems are that applications are moved to the Internet as web applications, and that computer systems are getting an increasing number of cores to increase the performance. It has been shown that JavaScript in web applications has a large potential for parallel execution despite the fact that JavaScript is a sequential language. LÄS MER

4. 3. Lightweight Enforcement of Fine-Grained Security Policies for Untrusted Software

   Författare :Phu Phung; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; security policy enforcement; JavaScript security; web-application security; vehicle software security; untrusted software;

   Sammanfattning : This thesis presents an innovative approach to implementing a security enforcement mechanism in the contexts of untrusted software systems, where a piece of code in a base system may come from an untrusted third party. The key point of the approach is that it is lightweight in the sense that it does not need an additional policy language or extra tool. LÄS MER

5. 4. Evaluating JavaScript Execution Behavior and Improving the Performance of Web Applications with Thread-Level Speculation

   Författare :Jan Kasper Martinsen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis addresses two issues: (i) The execution behavior of JavaScript in established benchmarks and in real-world Web Applications and (ii) whether Thread-Level Speculation is a suitable technique for taking advantage of multicore systems in Web Applications written in JavaScript. The first key result is that JavaScript execution behavior by the benchmarks and the JavaScript execution behavior by the Web Applications differ in several important aspects. LÄS MER

7. 5. Securing Software in the Presence of Third-Party Modules

   Författare :Seyed Mohammad Mehdi Ahmadpanah; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Third-Party Modules; JavaScript Runtime Monitor; Trigger-Action Platforms; Nontransitive Noninterference; Information-Flow Control;

   Sammanfattning : Modular programming is a key concept in software development where the program consists of code modules that are designed and implemented independently. This approach accelerates the development process and enhances scalability of the final product. LÄS MER
