ePrint ReportTight proofs of space are necessary for proof-of-replication (PoRep), which is a publicly verifiable proof that the prover is dedicating unique resources to storing one or more retrievable replicas of a file. Our main PoS construction can be used as a PoRep, but data extraction is as inefficient as replica generation. We present a second variant of our construction called ZigZag PoRep that has fast/parallelizable data extraction compared to replica generation and maintains the same space tightness while only increasing the number of levels by roughly a factor two.

ePrint ReportThis paper focuses on secure sketch. We propose a new technique to generate re-usable secure sketch. We show security to low entropy sources and enable error correction up to Shannon bound. Our security defined information theoretically with fuzzy min-entropy under distribution uncertain setting. In other words, our new technique offers security guarantee for all family of input distribution, as long as the sources possessing ``meaningful amount" of fuzzy min-entropy over some random distributions, parametrized by a chosen error correction code.

ePrint ReportOur attack extends the number of previously attacked rounds by 4 and has a success probability 1. This reduces the security margin of both these ciphers to 16%. Up to our knowledge, this is currently the best attack on Simon-32/64 and Simeck-32/64.

JP Morgan - ROAR Data
Job PostingWe’re guessing you know that one. If you enjoy privacy preserving computation and recognize the potential, you might want to join a team of top tier engineers, data scientists, mathematicians and cryptographers working on the ROAR platform. You will collaborate across engineering and business units to help build a next-generation prediction platform used by the bank, the bank’s clients, and eventually - we hope - the entire world.
You will:
• Design, implement and improve techniques for privacy preserving Machine Learning using whatever techniques are most appropriate (cryptographic, statistical and a combination of the two).
• Design, implement and improve partial structure preserving data obfuscation methodologies
• Design and analyze hypothetical statistical attacks, real and hypothetical
• Design and build into our contest framework new primitives, and combinations of the same, to expand the possibilities for crowd-sourcing data, predictions and models.
• Work with leading experts in secure multiparty computation.
• Collaborate with researchers and students as part of the JP Morgan/ ROAR partnership with MIT, which involves Sloan CIDL and MIT CSAIL.
• Adapt privacy methods to real-time data streams.

ePrint ReportInspired by the courts' accountability challenge, we illustrate how accountability and secrecy are simultaneously achievable when modern cryptography is brought to bear. Our system improves configurability while preserving secrecy, offering new tradeoffs potentially more palatable to the risk-averse court system. Judges, law enforcement, and companies publish commitments to surveillance actions, argue in zero-knowledge that their behavior is consistent, and compute aggregate surveillance statistics by multi-party computation (MPC). We demonstrate that these primitives perform efficiently at the scale of the federal judiciary. To do so, we implement a hierarchical form of MPC that mirrors the hierarchy of the court system. We also develop statements in succinct zero-knowledge (SNARKs) whose specificity can be tuned to calibrate the amount of information released. All told, our proposal not only offers the court system a flexible range of options for enhancing accountability in the face of necessary secrecy, but also yields a general framework for accountability in a broader class of "secret information processes."
