We have provided some project examples on secure email communications using ns3:

End-to-End Encryption Implementation:
- We had simulated an email communication system where end-to-end encryption is implemented using protocols like PGP (Pretty Good Privacy) or S/MIME (Secure/Multipurpose Internet Mail Extensions).
- The performance has been analyzed impact on email delivery time and system overhead.
Secure Email Gateway Simulation:
- To filter and encrypt emails at the network boundary we had developed a secure email gateway.
- The effectiveness in preventing data leaks and securing email communications has been evaluated.
TLS (Transport Layer Security) in Email Transmission:
- For secure email transmission between email clients and servers we had implemented TLS.
- The impact on email delivery time, latency, and security against man-in-the-middle attacks has been assessed.
Phishing Detection and Prevention:
- We had simulated an email system with built-in phishing detection mechanisms.
- The effectiveness of various algorithms (e.g., machine learning-based, heuristic-based) has been evaluated in detecting and preventing phishing attacks.
Email Integrity and Authentication with DKIM and DMARC:
- We had implemented DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting & Conformance) protocols.
- The impact on email authentication, integrity, and reduction of spoofed emails has been analyzed.
Spam Filtering with Bayesian Analysis:
- We had developed and simulated a Bayesian spam filtering system for email communications.
- The accuracy and performance of the filter in distinguishing between legitimate emails and spam has been evaluated.
Secure Email Storage and Retrieval:
- We had implemented a secure storage mechanism for emails using encryption.
- The impact on retrieval times and storage overhead has been evaluated.
Secure Email Protocol Comparison:
- The security and performance of different secure email protocols (e.g., PGP, S/MIME, TLS) has been compared under various network conditions.
- In terms of security, performance, and user experience, we had analyzed the trade-offs.
Encrypted Email Attachments Handling:
- We had simulated a system that ensures email attachments are encrypted before transmission and decrypted upon receipt.
- Assess the impact on performance and security of the email system.
Email Anonymity with Onion Routing:
- For email communications we had implement onion routing to ensure anonymity and privacy.
- The impact on latency and the effectiveness in protecting user identities has been evaluated.
Multi-Factor Authentication for Email Access:
- Develop a multi-factor authentication system for accessing email accounts.
- Simulate its impact on security and user experience.
Intrusion Detection in Email Servers:
- Implement an intrusion detection system (IDS) to monitor and detect suspicious activities in email servers.
- We can identify and mitigate threats by evluating the system’s effectiveness.
Resilience Against DDoS Attacks on Email Servers:
- Simulate DDoS attacks on email servers and implement mitigation techniques.
- The effectiveness of various defense mechanisms in maintaining email service availability has been evaluated.
Privacy-Preserving Email Analytics:
- For performing analytics on email data while preserving user privacy through techniques like homomorphic encryption we had developed a system.
- The trade-offs between privacy and the utility of analytics results has been evaluated.
Policy-Based Secure Email Communication:
- For secure email communication that enforces organizational security policies we had implemented a policy-based system.
- The system’s impact on compliance, security, and usability has been assessed.

Here we have used Secure Email gateway simulation, TLS transmission, Authentication with DKIM and DMARC, Email Anonymity with Onion routing, Multi factor Authentication for email access for implementing Secure email communication in ns3.
