Sample text

When implementing SME for a browser, an important design choice is how to deal with the Document Object Model API, the API to interact with the web page that the browser exposes to scripts. On the one hand, one can multi-execute the entire browser, and hence DOM API interactions become internal interactions: each SME copy of the browser will have its own copy of the DOM. This is essentially what Bielova et al. and Capizzi et al. do in their implementations. An alternative is to only multi-execute the scripts, and to treat the interactions with the DOM API as inputs and outputs.

Executions that are allowed to see the input just proceed as before. For executions with a lower security level than that of the input channel, we simply skip the operation (which would result in an undefined as in the example in Section 4). g. the empty string. Input with side effects. g. reading the response from a prompt call), we have to store the input data in order to reuse it on a later point in time in other executions. Skipping of DOM API calls can be implemented very generically: We modified the XPConnect layer to intercept all possible DOM API calls and to mediate their execution.

This is essentially what Bielova et al. and Capizzi et al. do in their implementations. An alternative is to only multi-execute the scripts, and to treat the interactions with the DOM API as inputs and outputs. In the next Section, we report on an implementation that takes this approach. 2 with support for secure multi-execution. This web browser is maintained by the Mozilla Corporation and is currently the second most widely used browser [42]. The components most relevant for our implementation are the following ones: Better Security and Privacy for Browsers 29 XPCOM.
