A Publicly Verifiable Leveled Fully Homomorphic Signcryption Scheme
IET Information Security, 2023 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 hybrid signcryption [PDF]
Mathematical and Computer Modelling, 2009 Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In this paper, we address a question whether it is possible to construct a hybrid signcryption scheme in the ...

Certificateless signcryption [PDF]
Proceedings of the 2008 ACM symposium on Information, computer and communications security, 2008 Certificateless cryptography inherits a solution to the certificate management problem in public-key encryption from identity-based techniques, whilst removing the secret key escrow functionality inherent to the identity-based setting. Signcryption schemes achieve confidentiality and authentication simultaneously by combining public-key encryption and ...

Stochastic Bat Optimization Model for Secured WSN with Energy‐Aware Quantized Indexive Clustering
Journal of Sensors, Volume 2023, Issue 1, 2023., 2023 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.

Securing Topology Control in SDWSNs Using Identity‐Based Cryptography
Journal of Sensors, Volume 2023, Issue 1, 2023., 2023 In software‐defined wireless sensor networks (SDWSNs), topology control is a fundamental procedure to maintain the global network topology. However, the open wireless channels of SDWSNs make it possible for an attacker to eavesdrop, replay, or modify the topology messages, thus posing a great threat to the network operations.

Blockchain‐Based Privacy‐Preserving Sensor Data Sharing with Fine‐Grained Authorization in Microgrid
Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 Microgrid is a power system that includes various energy sources (e.g., solar panels and wind turbines), where a number of device status and sensing data are collected and transmitted by smart sensors. Based on sensing‐as‐a‐service in microgrid, sensor owners and sensor data consumers can effectively perform data sharing operations.
