Privacy‐preserving multi‐receiver signcryption scheme for heterogeneous systems

Abstract

In recent years, secure communication and privacy‐preserving are gaining popularity because of the advent of wireless network. Certificateless cryptography (CLC) and identity‐based cryptography (IBC) have already been widely applied in the area of wireless network. Hence, to achieve secure communication from CLC to IBC, we present a heterogeneous signcryption scheme that enables a sender in the CLC to transmit a message to multi‐receiver in the IBC. Our scheme has no restrictions on the system parameters and master keys; private key generator and key generating center generate their own system parameters and master key for the IBC users and the CLC user, separately. Considering privacy‐preserving in heterogeneous communication, we show that our scheme can realize the anonymity of all receivers. Compared with other schemes, our scheme has more advantages, such as public verification and decryption fairness, which are attractive for wireless network applications. Moreover, our scheme has the indistinguishability against adaptive chosen ciphertext attacks, the existential unforgeability against adaptive chosen messages attacks, and anonymous indistinguishability of encryptions under selective‐ID, chosen ciphertext attack in the random oracle model.

A Lightweight Multi-Message and Multi-Receiver Heterogeneous Hybrid Signcryption Scheme based on Hyper Elliptic Curve

“…In this subsection we make a comparison of our designed multi-message and multireciever with existing schemes [43], [44]. The computational cost can be computed in term most costly operations such as bilinear pairing ( ), multiplication operation of pairing ( ), elliptic curve multiplication ( ) and modular exponential ( ).…”

“…The fast advance of the internet requires different message corresponding over the more extensive territory to enhance the heterogeneous network security. To deal with these like circumstances, enhance the selection of the security prerequisites and to build the speed of data transmission for numerous messages, multi-messages signcryption were presented [40]- [43]. Recently, Shufen et al [44] designed a Heterogeneous hybrid signcryption scheme for transmitting multi-messages to multi-receiver group.…”

“…After, successful generation of signcryptext, then it delivered the same copy of signcryptext to multiple group. Recently, heterogeneous signcryption mechanisms have got significant attention in so many cryptographic applications [34]- [37]. It is a viable means for extensive messages to utilize hybrid encryption to create secure communication.…”

An Efficient Heterogeneous Signcryption Scheme from Certificateless to Identity-based Cryptosystem

“…Our program is written in with the PBC library [17], and we run on a personal computer with 3.10GHz CPU and 2GB of RAM, using Linux operating system. In order to the effect of comparison, we will adopt Y Li et al [11]. Both schemes are set up in heterogeneous system, and both the schemes use different system parameters.…”

“…In 2016, Li et al [11] proposed a multi-receiver signcryption scheme for heterogeneous systems. Their work provided inspiration for the current study.…”
