The article proposes one-pass authenticated key establishment protocol in random oracles for Wireless Sensor Networks. Security of the protocol relies on Computational Diffie-Hellman Problem on Bilinear Pairings. In one-pass key establishment protocol, the initiator computes a session key and a related message. The key token is to be sent to the intended receiver using receiver's public key and sender secret key. From the received key token the receiver compute the session key, which is the same as the one computed by the sender, using sender public key and receiver's secret key. Because of low communication overhead, the scheme is better suited for Wireless Sensor Networks(WSNs) than the traditional key establishment protocol to establish the session key between two adjacent nodes

Climate literacy is crucial to increasing public understanding and engagement with the global climate catastrophe. However, current climate education approaches often fail to effectively raise concern and action, particularly across diverse age groups. This study makes a modest attempt to detail the design and development of a novel multilevel interactive digital climate education platform for early learners, adolescents, and adults using adaptive learning pathways, personalized content delivery, multimedia interactivity, and gamification features to promote learner engagement as well as learning outcomes across different age levels. A mixed-methods research design was used involving pre and post-survey quantitative measures as well as qualitative user experience testing. Post-survey results indicated significant improvement in climate literacy knowledge, attitudes towards the environment, and self-efficacy
