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...

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...
Abstract. In this paper, we propose a signcryption scheme which provides all the following properties at the same time. (1) forward security: the private key of a sender does not h...
Abstract. Signcryption as a single cryptographic primitive offers both confidentiality and authentication simultaneously. Generally in signcryption schemes, the message is hidden a...

Certificateless cryptography achieves the best of the two worlds: it inherits from identity-based techniques a solution to the certificate management problem in public-key encrypti...
