Impossibility of program obfuscation
WitrynaThe main ingredient in our technique is a new impossibility result for general program obfuscation. The results extend the impossibility result of Barak et al. (CRYPTO 2001) to the case of obfuscation with approximate function-ality; thus, settling a question left open by Barak et al.. In the converse direction, we show a generic transformation WitrynaThe basic impossibility result as described above applies to obfuscators Ofor which we require that the obfuscated program O(P) computes exactly the same function as the original program P. However, for some applications it may suffice that, for every …

Witryna1 lis 2015 · ally, an obfuscated program should be a “virtual black box,” in the sense that anything one can compute from it one could also compute from the input-output behavior of the program. The hope that some form of obfuscation is possible arises from the fact that analyz-ing programs expressed in rich enough formalisms is hard. … WitrynaThe problem of program obfuscation, which practition-ers have been engaged in for many years, has recently re-ceived attention in the theoretical community as well. …

Tauman Kalai, On the impossibility of obfuscation with auxiliary input, in FOCS 2005 (2005), pp. 553-562. Google Scholar; WitrynaSahai believes further work may revive the concept of VBB obfuscation. "The impossibility result was overinterpreted by the community at large," he says, on the …
WitrynaIt can make debugging issues after the software has been obfuscated extremely difficult. Once code becomes abandonware and is no longer maintained, hobbyists may want to maintain the program, add mods, or understand it better. Obfuscation makes it hard for end users to do useful things with the code.

As they travel from room to ... solarplane für pool rund 450Witrynaobfuscated program cannot do better than a simulator that is given only black-box access to the program. Barak et al. constructed contrived function families that cannot be VBB obfuscated, thus ruling out a universal obfuscator, but they left open the possibility that large classes of programs might still be obfuscated. slv more than lightWitrynaobfuscated program is a “virtual black box.” That is, anything one can efficiently compute from the obfuscated program, one should be able to efficiently compute … solar pir led lightslvnv:simcoverage:simulationfailedWitrynaThe problem of program obfuscation concerns the task of rewriting programs in a way that makes their code “unintelligible” without destroying its functionality. … slvms bell scheduleWitryna12 mar 2024 · Maybe Sketch is not officially exposing its APIs, but certainly the way in which they have built the internal structure of their files is a sort of «unofficial» API.
