Efficient and Secure DVPS Scheme with Message Recovery Based on ECDLP

One type of digital signature is one that has a designated verifier sig- nature (DVS). By assigning their signing authority to another user, a user may allow that other user to sign messages on their behalf using a DVPS (Designated Verifier Proxy Signature) system. The only person who can verify the authenticity of the generated signatures is the designated ver- ifier. To date, numerous methods have been developed for designated verifier proxy signatures. This paper proposes message recovery and an efficient and secure DVPS scheme based on ECDLP. Although the pro- posed scheme meets the requirements of a proxy signature scheme, it is also fast and safe to use. Its performance is compared to those of Rongxing Lu et al. [20] and Sahadeo Padhye et al. [17]
