Title: T-PKI: a Signature Scheme based on Public Key Infrastructure with Many Unlinkable Public Keys

Abstract: This research focuses on a family of problems where peer-to-peer transactions need to stay anonymized in a shared open platform such as a public blockchain or commerce sites such as eBay. This anonymization is meant to preserve the identity of the participants and prevent information leakage as a result. The publicly available platform can be used and accessed by several users, and potentially rogue actors. The leakage of information may lead to privacy violation or disclosure of confidential information, and thus needs to be protected. This research aims to consider the solution set that can solve the deanonymization of participants in peer-to-peer networks. The solution will reduce the digital footprint of a set of transactions by creating a model where each transaction is separate and distinct, yet providing a mechanism for the participants to keep track of the transactions efficiently and predictably. This would prevent an eavesdropper from relating the transactions to each other or the participants. The solution should also allow for terms of the transaction (transaction data) to be retrievable at a later point in time for dispute resolution.
