Signcryption is a cryptographic primitive which provides unforgeability and confidentiality for
digital communications. Many signcryption schemes have been constructed in the literature …

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 …

With the limited resources of the Internet of Things (IoT), security and efficiency have
become a challenge. The hybrid signcryption scheme is a proper method to ensure data …

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 …

Certificateless hybrid signcryption is a newly cryptosystem that plays a great role in some
storage-constrained networks when confidentiality and authenticity are needed …

Through the cryptanalysis of a signcryption scheme without bilinear pairing proposed by
Gao et al.(GAO J, WU X, QIN Y. Secure certificateless signcryption scheme without bilinear …

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

Signcryption achieves both encryption and digital signature at the same time. The cost of the
computations involved and the overheads involved in the communication is smaller than the …
