Analysis of disassembled executable codes by abstract interpretation
The aim of this paper is to dene the abstract domain, abstract operator, abstract semantic, the environments and states of disassembled executable codes as well as a way to analysis the disassembled executable codes. Nowadays, static analysis on disassembled code going to grow. Reverse engineering and malware analysis use this technique. Thus, we tried to perform pluralization the requirements ...
متن کاملReverse Engineering of Network Software Binary Codes for Identification of Syntax and Semantics of Protocol Messages
Reverse engineering of network applications especially from the security point of view is of high importance and interest. Many network applications use proprietary protocols which specifications are not publicly available. Reverse engineering of such applications could provide us with vital information to understand their embedded unknown protocols. This could facilitate many tasks including d...

متن کاملAutomatic Verification by Abstract Interpretation
We discuss the use of abstract interpretation in the context of automatic program veri cation requiring precise abstractions. We compare entirely manual versus user-guided abstractions ranging from program-speci c abstractions including predicate abstraction to the systematic design of abstract domains and iteration strategies. 1 Abstract Interpretation Theory Abstract interpretation theory [1,...
متن کاملA New Interpretation of the Semantics of "Moral Obligation" from Allame Tabatabaie's Viewpoint
The most important part in analyzing moral concepts includes those used as predicate in moral sentences covering moral concepts of valuation and obligation. Moral concepts in the field of values include those like “good” and “bad” while obligatory concepts include “ought to” and “ought no” and “duty”. Many papers have been written about “moral obligation”; however, dissociating the area of sema...
متن کاملDeclarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...
