Provable Secure Generalized Signcryption [PDF]
Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an en- cryption scheme, a signature scheme or a signcryption scheme[5]. However,the security proof in their paper is uncorrect. our contribution are as following:First we give security notions for this new primitive.Secnond,we give an attack to [4] which ...

A Publicly Verifiable Leveled Fully Homomorphic Signcryption Scheme
With the deepening of research, how to construct a fully homomorphic signcryption scheme based on standard assumptions is a problem that we need to solve. For this question, recently, Jin et al.

Certificateless Generalized Signcryption
AbstractGeneralized Signcryption is a fresh cryptographic primitive that not only can obtain encryption and signature in a single operation, but also provide encryption or signature model alone when needed. This paper proposed a formal definition of certificateless generalized signcryption(CLGSC), then provide the security model of CLGSC.

A secure anonymous proxy signcryption scheme
We introduce a new cryptographic primitive identity-based anonymous proxy signcryption which provides anonymity to the proxy sender while also providing a mechanism to the original sender to expose the identity of the proxy sender in case of misuse.

Generic Constructions for Verifiable Signcryption [PDF]
Signcryption is a primitive which simultaneously performs the functions of both signature and encryption in a way that is more efficient than signing and encrypting separately. We study in this paper constructions of signcryption schemes from basic cryptographic mechanisms; our study concludes that the known constructions require expensive encryption ...

Hybrid lightweight Signcryption scheme for IoT
The information transmitted in IoT is susceptible to affect the user’s privacy, and hence the information ought to be transmitted securely. The conventional method to assure integrity, confidentiality, and non-repudiation is to first sign the message and

SIS‐AODV consist of Ant Colony Grey Wolf Optimisation (ACGWO) over AODV algorithm to improve network performance while implementing security algorithm over MANET. Analysis results shows maximum performance with the PDR of 98% and throughput of 85%. In addition, end‐to‐end delay is reduced up‐to 25% and routing overhead decrease up‐to 20%. Abstract In a

Improved SRP algorithm and bidirectional heterogeneous LTE‐R authentication key
LTE‐R is the next generation of high‐speed railway wireless communication system in China, and its security is of important practical significance to ensure safe operation of trains. Animproved SRP algorithm and a two‐way heterogeneous LTE‐R authentication key agreement scheme are proposed.

Stochastic Bat Optimization Model for Secured WSN with Energy‐Aware Quantized Indexive Clustering
The wireless sensor networks (WSNs) with dynamic topology communication among the sensor nodes is vulnerable to numerous attacks. As they have limited power, there arises a conflict between the complex security scheme and the consumption of energy which are inversely proportional to each other.
