wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

What are the real security issues of wireless communication and wireless sensor networks in particular? Despite predictions of wireless sensor networks being deployed in many aspects of everyday life, real world deployments are still quite sparse. It seems that monitoring of large civil engineering structures is one of the few applications where wireless sensor networks may give enough value fo...

The use of unified communication; video conferencing, audio and instant messaging has skyrocketed during the COVID-19 pandemic. However, security privacy considerations have often been neglected. This article provides a comprehensive survey in Unified Communication (UC). We systematically analyze threats mitigations generic UC scenario. Based on this, we features major market leaders, draw conc...
