Impossibility of program obfuscation
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 Once code becomes abandonware and is no longer maintained, hobbyists may want to maintain the program, add mods, or understand it better.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. Witrynaimpossibility theorem [Ric53] which did not dishearten the development of methods and tools for automatically proving program correctness, the impossibility of VBB obfuscation represents a major challenge in developing practical methods for hiding sensitive information in programs that guarantee secure non-disclosure, e.g., for a

Witryna25 paź 2005 · On the impossibility of obfuscation with auxiliary input Abstract: Barak et al. formalized the notion of obfuscation, and showed that there exist (contrived) classes of functions that cannot be obfuscated. In contrast, Canetti and Wee showed how to obfuscate point functions, under various complexity assumptions. Witrynaobfuscated program is a “virtual black box.” That is, anything one can efficiently compute from the obfuscated program, one should be able to efficiently compute given just oracle access to the program. Our main result shows that it is impossible to achieve this notion of obfuscation. We prove this
Witryna11 sie 2024 · Obfuscation is useful for publishing software without revealing the code, but it also has more fundamental applications in cryptography. For example, the strongest notion called virtual black-box obfuscation can transform any private-key encryption scheme into a public-key scheme, and transform public-key schemes into fully … 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 …
Witryna22 sie 2024 · Key-based circuit obfuscation or logic-locking is a technique that can be used to hide the full design of an integrated circuit from an untrusted foundry or end-user. The technique is based on creating ambiguity in the original circuit by inserting “key” input bits into the circuit such that the circuit is unintelligible …
