最近做和PAKE相关的工作,找出来一堆UC下做password authenticated secret sharing(PASS)的论文。以Camenisch et al 这篇[1]中的构造为代表,大部分以DDH/CDH假设的构造都用了两个工具: 1)ElGamal加密; 2)zero knowledge proof (ZKP)。ZKP里所用到的技术相对而言没有那么新,但构造非常有启发性。这篇先回顾PASS...
The most popular interactive or non-interactive zero-knowledge proof (e.g., zk-SNARK) protocols can be broadly categorized in the following four categories: Succinct Non-Interactive ARguments of Knowledge (SNARK), Scalable Transparent ARgument of Knowledge (STARK), Verifiable Polynomial Delegation (VPD...

More precisely, we propose new NIZKs for proof of knowledge of x, x1, x2, y1, y2 such that – f1(x1, f2(x2)) = z, – f1(x, y1) = z1 AND f2(x, y2) = z2, – f1(x, y1) = z1 OR f2(x, y2) = z2, for public values z, z1, z2, and where f1 and f2 can...
Metal Gear Wiki Top Pages this Week 2 , Page 058. 監督からは「車椅子でラストに登場する」と、シンプルなオーダーでした。フィニッシュはやはり内山君にお願いしています。 CGモデラーと話していても比較的スムーズに制作が進んだ感じです。しわが多いほど作りやすいんですね。モデリン...
In simple words, everything you do on a Zero Knowledge system is encrypted before it is sent to the server and the key to the encryption is also never revealed to the vendor. Zero knowledge algorithms and protocols ensure that no keys, passwords, files, or any other sensitive material ever...
Constantine: High performance cryptography for proof systems and blockchain protocols “A cryptographic system should be secure even if everything about the system, except the key, is public knowledge.” — Auguste Kerckhoffs This library providesconstant-timeimplementation of cryptographic primitives with...

Encourage collaboration across different prospectives to bring fresh paths to push solutions. Knowledge sharing, use the #4opens to clear meaningful paths to move outside the current clutter. Create platforms for sharing this knowledge, run workshops, webinars, and hackathons, to facilitate “native...
