With the speedy growth of the populace, corresponding waste also grows, notably raising greater concern about the monitoring of waste in urban areas. Although the traditional method of waste monitoring has benefited city waste management systems, it remains timeâconsuming, inefficient, and detrimental to public health. This situation can be improved by integrating advanced technologies, which can significantly enhance the flexibility and performance of waste monitoring systems. However, these advanced technologies encounter numerous security challenges. In this article, we have implemented a signatureâbased monitoring approach to oversee the status of smart bins. To ensure the security, robustness, and reliability of the introduced protocol, we utilized tools such as AVISPA, Scyther, the ROR model, and Mao and Boyd logic. As discussed in the informal security analysis, the introduced protocol successfully fulfills the security requirements for smart waste monitoring systems. Finally, an inâdepth comparative analysis of the related works and the introduced protocol shows that the latter provides greater security, reliability, and efficiency. As a result, the reliability and hardness of the cryptographic operations used in the introduced protocol make it secure enough to use in realâworld applications.
