Secret Sharing With Trusted Third Parties Using Piggy Bank Protocol

TL;DR

This paper introduces a novel secret sharing scheme involving two trusted third parties using the piggy bank protocol, enhancing security and enabling law enforcement access, with potential applications in classical and quantum systems.

Contribution

It proposes a new multi-party secret sharing protocol with increased security and law enforcement access, extending piggy bank cryptography to multiple trusted parties.

Findings

Enhanced security by involving two trusted third parties

Protocol enables law enforcement access to sensitive data

Potential applicability to quantum cryptographic schemes

Abstract

This paper presents a new scheme to distribute secret shares using two trusted third parties to increase security and eliminate the dependency on single trusted third party. This protocol for communication between a device and two trusted third parties uses the piggy bank cryptographic paradigm. We also present a protocol to give law enforcing agencies access to sensitive information present on a cell phone or a device using secret sharing scheme. The ideas for classical systems may also be applied to quantum schemes.
