Now-a-days, users have a huge awareness on their privacy which is resulting in increase of the anonymity. Anonymity is the quality or state of being unknown or unacknowledged. It provides protection for the users to use the network services without being traced. Even the tracing does not happen, sometimes if any conditional anonymity like misbehaving entities in the network occurs, the network authority keeps such entities traceable.

In this project, security architecture is proposed to ensure the unconditional anonymity for honest users and trace the misbehaving users by trusted authorities in Wireless Mesh Networks (WMNs). The proposed system architecture can be used to resolve the problems faced between anonymity and traceability. It also provides fundamental security requirements like authentication, confidentiality, data integrity, and non-repudiation. A thorough analysis has been done on security and efficiency, demonstrating the feasibility and effectiveness of the proposed system architecture.

Introduction

The increasing awareness and concern for privacy among network users have led to a pressing need for solutions that protect user anonymity without compromising security. Wireless Mesh Networks (WMNs) serve as an ideal platform for implementing such solutions due to their decentralized nature and flexibility. Ensuring unconditional anonymity for honest users while enabling the tracing of misbehaving entities is a critical security challenge addressed by this project.

Literature Review

Existing approaches to anonymity in wireless networks primarily focus on either providing guaranteed privacy or enabling accountability. Traditional anonymization techniques, such as mix networks and onion routing, provide strong privacy but fall short when it comes to tracing malicious activities. Conversely, traceability mechanisms often weaken privacy protections, making users susceptible to profiling.

Recent advancements have proposed hybrid models that integrate anonymity and traceability using cryptographic schemes such as group signatures and traceable pseudonyms. However, these solutions often involve significant computational overhead and may not effectively balance privacy with accountability.

Proposed System Overview

The proposed security architecture employs a trust-based framework combining cryptographic techniques to achieve unconditional anonymity for honest users and traceability for misbehaving ones. In this architecture, trusted authorities manage user credentials through a secure registration process, employing group signature schemes to facilitate anonymous authentication.

Trust authorities maintain a secure database of user identities linked with pseudonyms. When a misbehavior is detected, they can invoke a traceability protocol to unmask the offending user while maintaining the anonymity of honest users. This approach ensures that privacy is preserved unless malicious behavior is identified, aligning with fundamental security requirements such as confidentiality, authentication, data integrity, and non-repudiation.

The system’s design incorporates secure channels for communication, robust encryption methods, and cryptographic proofs to ensure data confidentiality and integrity. The architecture leverages efficient cryptographic algorithms to minimize latency and computational overhead, making it feasible for real-world deployment.

Analysis and Effectiveness

Extensive security analysis demonstrates that the proposed architecture effectively resists common attacks such as eavesdropping, impersonation, and replay attacks. The cryptographic schemes employed provide strong guarantees for authentication and non-repudiation.

Efficiency analysis indicates that the system maintains low computational costs, enabling real-time performance suitable for WMNs. Simulations validate that the architecture can effectively balance user privacy protection with accountability, making it highly feasible for practical applications.

Conclusion

This project introduces a comprehensive security architecture designed to uphold unconditional user anonymity in wireless mesh networks while enabling authorities to trace misbehaving users when necessary. By integrating cryptographic mechanisms with trusted authorities, the architecture ensures adherence to security principles such as confidentiality, authentication, data integrity, and non-repudiation. The analysis confirms its feasibility and effectiveness, offering a robust solution for privacy-preserving security in mesh networks.
