A Directed Threshold - Signature Scheme

TL;DR

This paper introduces a threshold directed signature scheme that enables multiple authorized signers within an organization to collaboratively sign sensitive messages, ensuring security and approval requirements.

Contribution

It proposes a novel threshold directed signature scheme that combines directed signatures with threshold cryptography for organizational approval processes.

Findings

The scheme allows multiple signers to collaboratively sign messages.

It enhances security for sensitive organizational communications.

The scheme is suitable for applications requiring multiple approvals.

Abstract

Directed signature is the solution of such problems when the signed message contains information sensitive to the signature receiver. Generally, in many application of directed signature, the signer is generally a single person. But when the message is on behalf of an organization, a valid sensitive message may require the approval of several people. Threshold signature schemes are used to solve these problems. This paper presents a threshold directed signature scheme.
