The Communication Complexity Landscape of Information-theoretic MPC by Arpita Patra
Secure Multi-party Computation (MPC) is the standard-bearer and holy-grail problem in Cryptography that permits a collection of data-owners to compute a collaborative result, without any of them gaining any knowledge about the data provided by the other, except what is derivable from the result of the computation. Communication complexity is one of the most prominent complexity measures of MPC with information-theoretic security. In this talk, I will draw a high-level picture of how the communication complexity study progressed over the years and my contributions to this area.

Reliable Quantum Computing Needs Intelligent Software and Hardware| by Prof. Moinuddin K. Qureshi
มุมมอง 16วันที่ผ่านมา
Quantum computers can solve important problems that are beyond the capability of conventional computers. Quantum computing is at an inflection point where small systems with a few tens qubits have been demonstrated and the number of qubits is expected to increase to several thousand over the coming years. As qubits are low-energy devices, they are susceptible to high error-rates (in the range o...

Separating Broadcast from Cheater Identification by Dr. Yashvanth Kondi
มุมมอง 4328 วันที่ผ่านมา
Secure Multiparty Computation (MPC) protocols that achieve Identifiable Abort (IA) guarantee honest parties that in the event that they are denied output, they will be notified of the identity of at least one corrupt party responsible for the abort. Cheater identification provides recourse in the event of a protocol failure, and in some cases can even be desired over Guaranteed Output Delivery....

Advanced Encryption Scheme from Pairing-based Succinct Argument by Prof. Mingyuan Wang
มุมมอง 34หลายเดือนก่อน
In this talk, I will present two of our recent works that construct encryption schemes with advanced features (1) threshold encryption with silent setup and (2) batch (threshold) decryption. In particular, I will introduce a unified framework in our constructions, which builds on a witness encryption scheme tailored for pairing product equations. This witness encryption allows us to utilize the...
Efficiently Testable Circuits by Mr. Mirza Ahad Baig
มุมมอง 422 หลายเดือนก่อน
In this talk, I will present the notion of “Efficiently TestableCircuits” introduced in [ITCS23]. Informally, a circuit is testable if one can detect tampering with the circuit by evaluating it on a small number ofinputs from some test set. Our technical contribution is a compiler that transforms any circuit C into a testable circuit ( C’, T) for which we can detect tampering (from a class of a...

Batch Proofs are Statistically Hiding by Prof. Prashant Nalini Vasudevan
มุมมอง 552 หลายเดือนก่อน
Batch proofs are (possibly interactive) proof-systems that convince a verifier that x_1,…,x_t are in L, for some NP language L, with communication that is much shorter than sending the t witnesses. Batch proofs have been studied in various settings in recent years. In the case of statistical soundness (where the cheating prover is unbounded but honest prover is efficient), interactive solutions...
Rolling a dice on Blockchain at a discount by Dr. Pratyay Mukherjee
มุมมอง 952 หลายเดือนก่อน
Randomness is an important resource in computing. In the blockchain/web3 space, many decentralized finance (DeFi) and particularly gaming applications, such as Lottery, Poker etc. crucially require a good source of randomness. In this setting generating good randomness is particularly non-trivial - this is because the typical source of randomness relies on (computation on) private source, and i...
