Data-flow analysis is to find a solution to a set of safe-approximationdirected constraints on the IN[s]’s and OUT[s]’s, for all statements s. - constraints based on semantics of statements (transfer functions) - constraints based on the flows of control 关于转移方程约束的概念 分析数据...
三、Pointer Analysis via Datalog 了解了Datalog的基本语法和性质,我们就可以用它来实现声明式的指针分析算法。 关于声明式的指针分析算法,三个重要的部分如下: EDB: pointer-relevant information that can be extracted from program syntactically IDB: pointer analysis results Rules: pointer analysis rules Datalog ...
static program analysisfunctional verificationnon-functional propertiesmodel-based designStatic program analysis is a viable, sound and automatic technique to prove correctness properties about programs, both functional properties as well as non-functional properties. It is one of the techniques, highly ...
Program analysisFuzzingProtocol parsersFuzz testing is an effective and scalable technique to perform software security assessments. Yet, contemporary fuzzers fall short of thoroughly testing applications with a high degree of control-flow diversity, such as firewalls and network packet analyzers. In this...
analysis extended its utility and now it can be used for a number of reasons including security analysis. Static analysis has the advantage that it does not require physical access to the device whose firmware needs to be analyzed[32]. Hence, from this perspective it is a scalable solution. ...

Semantics-preserving program transformations, such as those carried out by an optimizing compiler, can affect the results of static program analyses. In the best cases, a transformation increases precision or allows a simpler analysis to replace a complex one. In other cases, transformations have ...
The lecture first introduced the live variables analysis. It is defined as: Live variables analysis tells whether the value of variable v at program point p could be used(and without any redefinition) along some path in CFG starting at p. If so, v is live at p; otherwise, v is dead ...

If we have constructed a PFG, then after all the transferring of the points-to information, the pointer analysis would be done. However as we can see, the construction of the PFG is somehow relies on the points-to information we need. In this context, the pointer analysis algorithm will ...
