| 2022 | Rate one-third non-malleable codesabstractAt ITCS 2010, Dziembowski, Pietrzak, and Wichs introduced Non-malleable Codes (NMCs) which protect against tampering of a codeword of a given message into the codeword of a related message. A well-studied model of tampering is the 2-split-state model where the codeword consists of two independently tamperable states. As with standard error-correcting codes, it is of great importance to build codes with high rates. Divesh Aggarwal, Bhavana Kanukurthi, Sai Lakshmi Bhavana Obbattu, Maciej Obremski, Sruthi Sekar |

| 2021 | Efficient Linear Multiparty PSI and Extensions to Circuit/Quorum PSIabstractMultiparty Private Set Intersection (mPSI), enables n parties, each holding private sets (each of size m) to securely compute the intersection of these private sets. While several protocols are known for this task, the only concretely efficient protocol is due to the work of Kolesnikov et al. (KMPRT, CCS 2017), who gave a semi-honest secure protocol with communication complexity O(nmtƛ), where t < n is the number of corrupt parties and ƛ is the security parameter. In this work, we make the following contributions: Nishanth Chandran, Nishka Dasgupta, Divya Gupta 0001, Sai Lakshmi Bhavana Obbattu, Sruthi Sekar, Akash Shah |
