ABSTRACT A certificateless (CL) signcryption scheme is a cryptographic primitive that
provides user authentication and message confidentiality at the same time. CL signcryption …

Signcryption is a cryptographic primitive that provides authentication (signing) and
confidentiality (encrypting) simultaneously at a lower computational cost and communication …

Signcryption is one of the recent public key paradigms that satisfies both the requirement of
authenticity and confidentiality of messages between parties. However, most of all the …

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 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 basically a cryptographic primitive which provides both signature and
encryption functions simultaneously, but it is not useful when only one of the function is …

Signcryption schemes offer the possibility to simultaneously sign and encrypt a message. In
order to guarantee the authentication of both signer and receiver in the most efficient way …

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

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 …
