About ProxyOT
Proxy Oblivious Transfer (ProxyOT) is a cryptographic protocol designed to enable secure data sharing between parties without revealing sensitive information. It builds upon the foundation of Oblivious Transfer (OT), a fundamental building block in cryptography that allows a sender to transfer one of potentially many pieces of information to a receiver, but remains oblivious as to which piece the receiver has received.
The "Proxy" enhancement in ProxyOT introduces a third party that facilitates the data transfer, making the protocol more flexible and efficient, particularly for applications like data marketplaces, secure data sharing in industries like healthcare and finance, and privacy-preserving distributed computing.
Our implementation is based on the paper "Proxy Oblivious Transfer Scheme for Secure Data Sharing Based on Blockchain," with different curve implementations provided in our repositories: the original BN256 curve implementation and an enhanced version using the BLS12-381 curve for improved security and performance.
