Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an encryption scheme, a signature scheme or a signcryption scheme [5]. However,the...
An efficient signcryption scheme based on elliptic curve is proposed in this paper. The signcryption scheme combines digital signature and encryption functions. The proposed schem...
An identity-based signcryption scheme with (t, n) shared unsigncryption is proposed, which is the integration of the signcryption scheme, the (t, n) threshold scheme and zero know...
The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Although...

Encrypt-and-sign, where one encrypts and signs a message in parallel, is usually not recommended for confidential message transmission. The reason is that the signature typically l...

Abstract. Signcryption is a public-key cryptographic primitive introduced by Zheng, which achieves both message confidentiality and nonrepudiatable origin authenticity, at a lower ...
