In cryptography, black-box obfuscation was a proposed cryptographic primitive which would allow a computer program to be obfuscated in a way such that it was impossible to determine anything about it except its input and output behavior. [1] Black-box obfuscation has been proven to be impossible, even in principle. [2]
In 2001, Barak et al., showing that black-box obfuscation is impossible, also proposed the idea of an indistinguishability obfuscator, and constructed an inefficient one. [8] [7] [2] Although this notion seemed relatively weak, Goldwasser and Rothblum (2007) showed that an efficient indistinguishability obfuscator would be a best-possible obfuscator, and any best-possible obfuscator would be ...
Test coverage refers to the percentage of software requirements that are tested by black-box testing for a system or application. [7] This is in contrast with code coverage, which examines the inner workings of a program and measures the degree to which the source code of a program is executed when a test suite is run. [8]
The concept of the black box is also important in actor–network theory as it relates to simplification. As Michel Callon notes, an actor-network is a system of discrete entities or nodes, while the reality that it represents is theoretically infinite. Therefore, in order to describe something in terms of an actor-network, complex systems must ...
Blackbox is a free and open-source stacking window manager for the X Window System. [5] [6] Blackbox has specific design goals, and some functionality is provided only through other applications. One example is the bbkeys hotkey application. Blackbox is written in C++ [4] [7] and contains completely original code. [8]
In academic discourse, the usage of the term “black box” dates back to at least 1963 with Mario Bunge's work on a black box theory in mathematics. [18]The term “black box,” as used throughout The Black Box Society by author and law professor, Frank Pasquale, is a dual metaphor for a recording device such as a data-monitoring system and for a system whose inner workings are secret or ...
Due to the polymorphic code used in generating variants of the Blackhole exploit kit, antivirus signatures will lag behind the automated generation of new variants of the Blackhole exploit kit, while changing the algorithm used to load malware onto victims' computers takes more effort from the developers of this exploit kit. A good HIPS will ...
The term "black box" is used because the actual program being executed is not examined. In computing in general, a black box program is one where the user cannot see the inner workings (perhaps because it is a closed source program) or one which has no side effects and the function of which need not be examined, a routine suitable for re-use.
