The Structure of Secure Multi-Party Computation
Secure multi-party computation is a conceptual framework in which distrusting parties engage in a protocol to securely perform a computational task. Depending on the precise model of security, different sets of tasks admit secure protocols. We take a complexity-theoretic approach to studying the …

Scaling asynchronous multi-party computation: A systems perspective
Modern multi-party computation applications no longer have a one-time execution pattern and instead are required to be run continuously like a service. They are deployed over the Internet which is inherently asynchronous and demand an infrastructure which is end-to-end robust, fault-tolerant and …

Practical Privacy-Preserving Federated Learning with Secure Multi-Party Computation
… has be- come increasingly important to offload computation intensive tasks to companies with the compute resources to perform training on potentially sensitive data. In applications such as finance or healthcare, the data providers may have a need to train large quantities of data, but cannot …

COMPARING PRIVACY-PRESERVING QUERY PROCESSING OVER OUTSOURCED ENCRYPTED DATA AND MULTI-PARTY COMPUTATION.
… literature these two solutions are referred to multi-party computation (MPC) and data outsourcing (DO), respectively. On the other hand, when no data owner or external service provider can be trusted enough to know all the inputs, privacy becomes a primary concern. To this purpose, data owners …

Thresholdizing lattice based encryption schemes
… we show how to construct paradigms of threshold multi-key fully homomorphic encryption and predicate encryption. Through multi-key fully homomorphic encryption [MW16] and threshold fully homomorphic encryption, we can construct a low-round multi party computation (MPC) scheme with guaranteed …

Privacy-preserving encoding for cloud computing
… trusted to protect user data. Privacy-preserving computation in the cloud keeps data private at all times but still remains functional, thus returning control of data back to users. The cloud could then perform operations using data that it cannot comprehend. The end-user would then be able to …

Efficient zero-knowledge range arguments and privacy-preserving applications
… significant challenges due to high gas costs and computational overhead. This part contributes to optimizing the {\em verification efficiency} of range arguments to reduce deployment costs on blockchains and other decentralized platforms. We introduce four new zero-knowledge range arguments in the …

Cloaking fabric, a confidentiality layer for hyperledger fabric
… Verifiable Secret Sharing(AVSS) and Secure Multi Party Computation(MPC) are techniques from cryptography that allow the sharing of secrets among multiple parties and enable arbitrary computations on the shared data without leaking any information about the data. Previously, AVSS and MPC …

Beyond traditional assumptions in fair machine learning
… To this end we devise protocols based on secure multi-party computation to train, validate, and contest fair decision algorithms without requiring users to disclose their sensitive data or decision makers to disclose their models. Finally, we also accommodate the fact that outcome labels are …

Efficient threshold cryptosystems
… that implement arithmetic operations, like multiplication or exponentiation, in a threshold setting. We exemplify this approach with two discrete-log based threshold schemes, a threshold DSS signature scheme and a threshold Cramer-Shoup cryptosystem. Our methodology leads to threshold …

Unified RAW Path Oblivious RAM
… trusted processors, software protection, secure multi-party computation, and so on. This thesis improves the state-of-the-art Path ORAM in several aspects. On the theoretical side, we improve Path ORAM's memory bandwidth overhead by a factor of O(log logN) when the block size is small. With this …
