Generalized signcryption is a new cryptographic primitive which is more useful than the common signcryption in some applications. In this paper, based on a short ECDSA, a sescure and efficient generalized signcryption scheme is proposed. It can work as ...
Multi-receiver signcryption is a new cryptographic primitive that simultaneously fulfills both the functions of signature and multi-receiver encryption. Generalized Multi-Receiver signcryption can provide authenticity or confidentiality separately under ...
Universal Designated-Verifier Signatures (UDVS) are proposed to protect the privacy of a signature holder. Since UDVS schemes reduce to standard signatures when no verifier designation is performed, from the perspective of a signer, it is natural ...
