Cryptography obfuscation
WebApr 27, 2024 · Obfuscation takes the source code and scrambles it in a way that it is possible to implement the designed algorithm (the output binary is compliant to the original), but in a way that it is very hard to understand the reversed code. About DRMs WebDec 29, 2024 · The story of cryptographic obfuscation is different. In 2001, we (Barak, Goldreich, Impagliazzo, Rudich, Sahai, Vadhan, and Yang) showed that what is arguably the most natural definition of obfuscation is impossible to achieve. That paper explored a number of obfuscation-related questions and in particular left as an open question the …
