Here’s a step-by-step procedure for replicating and measuring network encryption in OPNET:
Steps to Simulate Network Encryption Projects in OPNET
- Define the Project Objectives
- Specify the purpose of encryption: Describe whether the aim is to protected data transmission such as VPN, SSL/TLS or measure the performance effects of encryption.
- Identify key performance metrics: the key parameters such as network delay, throughput, CPU and memory usage, and packet loss.
- Set up the Network Topology
- Design the network layout: Utilize OPNET’s graphical interface to incorporate nodes such as routers, switches, servers, and client devices.
- Configure network protocols: configure essential protocols such as TCP/IP, HTTP, FTP and services like web browsing, file transfers to mimic usual network traffic.
- Implement Encryption Mechanisms
Select the suitable encryption approaches and protocols according to project objectives:
- VPN (Virtual Private Network):
- Set up VPN tunnels among network segments or between clients and servers to protect communication.
- Utilize an encryption protocols such as IPsec to encode data routed over the VPN.
- Validate the effects of different encryption techniques such as AES, DES and key lengths like 128-bit, 256-bit on network performance.
- SSL/TLS for Secure Web Traffic:
- Configure a secure web server and allow SSL/TLS encryption for HTTP traffic.
- Set up the encryption strength such as 128-bit or 256-bit and protocols to monitor the impact on data transfer speed and latency.
- Wireless Network Encryption (WPA2/WPA3):
- For wireless networks, set up Wi-Fi access points to utilize encryption protocols like WPA2 or WPA3.
- Measure the effects on data throughput, delay, and packet loss; specifically when manage large data transfers or concurrent connections.
- Configure Encryption Levels and Algorithms
- Experiment with encryption schemes: Utilize symmetric encryption such as AES and asymmetric encryption like RSA in altered parts of the network.
- Test different key sizes: Set up encryption keys of changing lengths (such as 128-bit vs. 256-bit) and relate the security level with the effects on network performance.
- Generate Application Traffic
- Simulate traffic flows: Utilize OPNET’s traffic generators to generate application-specific traffic like web, email, and file transfer over encrypted channels.
- Test mixed traffic: Set up some flows with encryption enabled like HTTPS and others without encryption such as HTTP to measure the performance differences.
- Set Up Monitoring and Data Collection
- Enable logging: Set up firewalls, routers, and end devices to log packet details, connection attempts, and timestamps for encodes and unencrypted traffic.
- Packet capture: Seizure packet-level data to evaluate differences in packet sizes, latency, and other features among encrypted and non-encrypted traffic.
- Collect performance metrics:
- Monitor parameters like delay, throughput, packet loss, and CPU and memory utilization on nodes serve as encryption/decryption.
- Run the Simulation and Capture Data
- Baseline simulation: Execute a model simulation with normal traffic to collect data on performance without encryption.
- Simulate with encryption: Establish encryption protocols and monitor the variation in parameters.
- Collect logs and performance data: Seizure data on throughput, delay, resource usage, and packet errors for evaluation.
- Analyse the Impact of Encryption
- Compare encrypted vs. unencrypted traffic: Evaluate the delay, throughput, and packet loss differences among encrypted and non-encrypted flows.
- Analyse resource utilization: Measure the effects on CPU and memory utilization for devices that includes in encryption and decryption.
- Security vs. Performance trade-off: Evaluate the balance among the improved security and potential performance reduction.
- Optimize Encryption Settings (Optional)
- Adjust encryption configurations: Validate different encryption techniques, key sizes, or allow hardware quickening if available on devices.
- Test scalability: upsurge the amount of encoded connections or traffic volume to validate how the network manage high loads with encryption.
- Generate Reports and Document Findings
- Visualization: Utilize OPNET’s data evaluation tools to plot graphs and charts relates to the effects of encryption on key parameters.
- Document results: Encapsulate encryption’s impacts on network effectiveness and deliver recommendations for balancing security and performance.
