Abstract. The heterogeneous signcryption can not only realize the confidentiality and un-forgeability of the information transmission between different public key cryptography environments, but also reduce the communication cost. The proposed scheme uses bilin-ear pairings between certificateless cryptography and identity-based cryptography to construct a heterogeneous signcryption scheme. In addition, two cryptography systems use different secret master keys. Furthermore, the proposed scheme has the indistinguishability against adaptive chosen ciphertext attacks and existential unforgeability against adaptive chosen-message attacks in the random oracle model. Through the data analysis, this scheme is more effective than other similar types of scheme.

Certificateless public key cryptography eliminates certificate management in traditional public key infrastructure and solves the key escrow problem in identity-based cryptography. Certificateless signcryption is one of the most important primitives in certificateless public key cryptography which achieves confidentiality and authentication simultaneously. Multi-receiver signcryption signcrypts a message to a large number of receivers. Selvi et al. proposed the first efficient and provably secure certificateless multi-receiver signcryption scheme. Recently, they found the scheme is insecure against the type I adversary and gave an enhanced one. However, we find that their enhanced scheme is still insecure against the type I adversary. In this paper, we present an attack on Selvi et al.'s enhanced scheme. Specifically, we show that a type I adversary can first replace a sender's public key and generate a signcrypted message on behalf of the sender.

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.
