Some Applications of Directed Signature Scheme

TL;DR

This paper explores two applications of directed signature schemes, including a delegated signature scheme combining proxy signatures and a secure registration number allocation method to prevent forgery.

Contribution

It introduces novel applications of directed signature schemes, notably a delegated signature scheme and a secure registration number allocation method.

Findings

Proposed a directed-delegated signature scheme combining proxy signatures.

Developed a registration scheme preventing forgery and misuse.

Demonstrated the applicability of directed signatures in secure registration processes.

Abstract

Directed signature scheme is applicable when the signed message contains information sensitive to the receiver, because only receiver can directly verify the signature and that he/she can prove its validity to any third party, whenever necessary. This paper presents two applications of directed signature scheme. (i) Directed –Delegated Signature Scheme. This scheme combines the idea of proxy signatures with directed signature scheme. (ii) Allocation of registration number. This scheme proposes a registration scheme in which the registration number cannot be forged and misused.
