From Single-Key to Collusion-Resistant Secret-Key Functional Encryption by Leveraging Succinctness
Secret-key functional encryption Collusion-resistance Succinctness
2017/7/4
We show how to construct secret-key functional encryption (SKFE) supporting unbounded polynomially many functional decryption keys, that is, collusion-resistant SKFE solely from SKFE supporting only o...
Indistinguishability Obfuscation for All Circuits from Secret-Key Functional Encryption
Indistinguishability obfuscation Secret-key functional encryption Puncturable secret-key functional encryption
2017/4/27
We show that indistinguishability obfuscation (IO) for all circuits can be constructed solely from secret-key functional encryption (SKFE). In the construction, SKFE need to be able to issue a-priori ...
Indistinguishability Obfuscation: Simpler Constructions using Secret-Key Functional Encryption
Indistinguishability Obfuscation Functional Encryption
2017/3/27
We propose simple generic constructions of indistinguishability obfuscator (IO). Our key tool is exponentially-efficient indistinguishability obfuscator (XIO), which is the same as IO except that the ...

Indistinguishability Obfuscation Functional Encryption
2016/6/6
Functional encryption lies at the frontiers of current research in cryptography; some variants have
been shown sufficiently powerful to yield indistinguishability obfuscation (IO) while other variant...
