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.

A Hyperelliptic Curve Cryptosystem Based Proxy Promised Signcryption Scheme

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
Signcryption is the method of combining a digital signature with encryption in a single logical step to get the cryptographic primitives of a public key. However, in addition to signcryption, we sometimes require anonymity and delegation of rights. In this paper, we propose a scheme called proxy promised signcryption to address all of these objectives ...
