“…Liu [17] in 2010 proposed a certificateless signcryption scheme in the standard model where he gives proof of his scheme being efficient and practical. How-ever, in 2011 J. Weng [18] proved that the scheme pro-posed by Liu et al is insecure under type-2 adversary at-tacks. Thereafter efforts were taken by many researchers to address the above issue but it did not proved to be successful.…”

Wireless Sensor Networks (WSN) is becoming the heart of many applications. Data integrity and security is a major issue as the wireless sensor nodes are exposed to harsh and hostile environment. This paper highlights the merits and demerits of different key management schemes under the broader classification of Public Key Infrastructure (PKI), Identity Based Encryption (IBE) and Certificateless Signcryption. These schemes will provide authentication and thereby secure the communication between the nodes considering the constraint environment of the wireless sensor network. Selection of these key management schemes depends upon the application specifications, functionality and computational complexity.

“…In 2010, Liu et al [18] proposed certificateless signcryption as an extension of ID-based signcryption. Unfortunately, Weng et al [19] showed that Liu et al's scheme is neither semantically secure against chosen ciphertext attacks nor existentially unforgeable against chosen message attacks.…”

Identity-based signcryption is a useful cryptographic primitive that provides both authentication and confidentiality for identity-based crypto systems. It is challenging to build a secure identity-based signcryption scheme that can be proven secure in a standard model. In this paper, we address the issue and propose a novel construction of identity-based signcryption which enjoys IND-CCA security and existential unforgeability without resorting to the random oracle model. Comparisons demonstrate that the new scheme achieves stronger security, better performance efficiency and shorter system parameters.

“…The scheme proposed by Yap et al [21] was shown insecure and modified by Li et al [13]. The design and analysis of Certificateless threshold signature schemes and certificateless signcryption schemes have also been studied in [5,22,14,17] respectively. In CL-PKC, a malicious-but-passive KGC [3] may be dishonest from the start of the system setup.…”
