In cryptography, indistinguishability obfuscation (abbreviated IO or iO) is a type of software obfuscation with the defining property that obfuscating any two programs that compute the same mathematical function results in programs that cannot be distinguished from each other. … Meer weergeven Let $${\displaystyle {\mathcal {iO}}}$$ be some uniform probabilistic polynomial-time algorithm. Then $${\displaystyle {\mathcal {iO}}}$$ is called an indistinguishability obfuscator if and only if it satisfies both of the following … Meer weergeven It is useful to divide the question of the existence of iO by using Russell Impagliazzo's "five worlds", which are five different … Meer weergeven • Black-box obfuscation, a stronger form of obfuscation proven to be impossible Meer weergeven The origin of this idea came from Amit Sahai in 1996 from the notion of a zero-knowledge proof. In 2001, Barak et al., showing that black-box obfuscation is impossible, also proposed the idea of an indistinguishability obfuscator, … Meer weergeven Indistinguishability obfuscators, if they exist, could be used for an enormous range of cryptographic applications, so much so that it has been referred to as a "central … Meer weergeven Web29 mrt. 2024 · iO(Indistinguishability Obfuscation,不可区分混淆)是密码学中黑科技一样的存在,它不仅可以隐藏数据集合,还可以隐藏计算机程序的内部工作机制,创造出强大的加密工具。但这种力量的强大让人们怀疑 iO 是否真的存在。
