Latest Patents

Pratik Sarkar holds a patent titled "Round optimal oblivious transfers from isogenies." This patent focuses on conducting secure transfers between computing devices using an oblivious transfer (OT) protocol. In this interactive protocol, a sender computing device holds two messages, m and m', while the receiver computing device holds a bit b, which can be either 0 or 1. At the conclusion of the protocol, the receiver learns only the message mb, without any knowledge of the other message m?b. Simultaneously, the sender remains unaware of the bit b. With advancements in quantum computing, several post-quantum oblivious transfer protocols can be derived from this work. Pratik's innovative approach is crucial for enhancing security in digital communications.
