In network system, cryptography is vital for securing communication. We can use network simulation tool provided by OMNeT++ to simulate a different cryptography methods and their applications in Network security. In the below, we provided some cryptography project samples that can be accomplished in OMNeT++:

1. Simulation of Secure Communication Using Symmetric Encryption

7. Simulation of Homomorphic Encryption for Secure Data Processing

• Objective: Permit estimation on encrypted data deprived of needing to decrypt it by simulating homomorphic encryption, ensuring data privacy even during processing.
• Implementation: Execute a network where data is encrypted before being sent to a processing node. The processing node achieves operations on the encrypted data and returns the result, which is decrypted by the receiving node.

9. Quantum Cryptography Simulation

• Objective: Simulate quantum key distribution (QKD) to make sure secure communication by misusing the principles of quantum mechanics.
• Implementation: Execute the basic version of the BB84 protocol in a network, where two nodes transmit quantum bits (qubits) to accomplish a shared secret key. Use this key for encrypting subsequent communication.

10. Simulation of Cryptographic Hash Functions for Data Integrity

• Objective: Simulate the use of cryptographic hash functions (like SHA-256) to ensure data reliability by configuring distinct hash values for data blocks.
• Implementation: Develop a network where data packets are hashed before transferred and the receiver certifies the hash value to make certain the data has not been interfered with.

11. Steganography and Cryptography in Network Communication

• Objective: Hide and secure messages inside other data streams like images or audio files, exchanged through the network by simulating the use of steganography concatenated with cryptography.

12. Simulation of Password-Based Cryptographic Security

• Objective: Mimic password-based encryption and decryption methods to protect data depend on user-generated passwords.
