Signcryption is a scheme that provides confidentiality and authentication while keeping
costs low in comparison to independent encryption and message sign ing. Since Zheng [13] …

Signcryption, which was introduced by ZHENG, is a cryptographic primitive that fulfils the
functions of both digital signature and encryption and guarantees confidentiality, integrity …

Hybrid signcryption is an important technique signcrypting bulk data using symmetric
encryption. In this paper, we apply the technique of certificateless hybrid signcryption to an …

Generalized signcryption can adaptively work as an encryption scheme, a signature
scheme, or a signcryption scheme with only one algorithm. The paper proposes an efficient …

Signcryption is a public key cryptographic primitive that performs digital signature and public
key encryption simultaneously, at lower computational costs and communication overheads …

Signcryption can realize encryption and signature simultaneously with lower computational
costs and communication overhead than those of the traditional sign‐then‐encrypt …

Certificateless signcryption has both the advan-tage of certificateless publick key
cryptography, which overcome the escrow problem inherited from identity based …

Signcryption is a very useful cryptographic primitive that aims to achieve authentication and
confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and …

Signcryption is a cryptographic technique that provides both confidentiality and authenticity
of data during public transmission in many modern applications like Internet-of-Things (IoT) …

Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and
public key encryption simultaneously, at a cost significantly lower than that required by the …
