WitrynaIt is known from prior work that general program obfuscation is possible with the help of a completely trusted hardware device (e.g., [7, 28, 19]). On the other hand, Barak et al. proved that software-only general program obfuscation is impossible, even for a very weak notion of obfuscation [6]. In this work we? Witryna19 gru 2015 · A celebrated result by Barak et al. (Crypto’01) shows the impossibility of general-purpose virtual black-box (VBB) obfuscation in the plain model. A recent work by Canetti, Kalai, and Paneth (TCC’15) extends this impossibility result to the random oracle model (assuming trapdoor permutations).
