Anonymous Communication Scheme for DTN Asynchronous Interactive Learning Environment

In the digital age, the security and privacy of col-laborative systems are increasingly critical. This paper examines the asynchronous interactive learning environment within Delay Tolerant Networks (DTN), which leverages satellite broadcasting in remote areas. However, this environment encounters challenges such as weak infrastructure, unstable connections, and security vulnerabilities associated with open networks. Additionally, traditional public key cryptosystems are susceptible to threats posed by quantum computing. To mitigate these issues, we propose an anonymous communication scheme based on lattice theory and pseudonyms, designed to enhance secure network communication for remote and impoverished areas through collaboration among communication entities in the DTN environment. Our security analysis and performance comparison demonstrate that the pro-posed scheme outperforms existing lattice-based solutions while maintaining essential security characteristics.
