How to Implement Mobile Application Security in NS2

To implement mobile application security in NS2 has needs to mimic numerous security protocols and approaches to secure mobile applications. Here’s a procedure on how to implement the mobile application security in ns2:

Step-by-Step Implementation:

  1. Understand the Security Features to Implement:
  • Authentication: Validate the identity of mobile application users.
  • Encryption: Secure interaction among mobile devices.
  • Intrusion Detection: Identify malicious activity in mobile networks.
  • Firewall Mechanism: Block unauthorized access.
  • Data Integrity: Make sure the data transmitted is not tampered with.
  1. Set up NS2:
  • Install NS2 on system. We can download it from NS2 Official Page.
  • Acquaint yourself with TCL scripts for simulation and C++ for underlying protocol modifications.
  1. Define the Simulation Scenario:
  • Model a mobile network topology with mobile nodes using AODV (Ad-hoc On-demand Distance Vector) or DSR (Dynamic Source Routing) as routing protocols.
  • Describe the nodes to denote mobile devices and configure the network metrics like mobility models, transmission range, etc.
  1. Implement Security Mechanisms:
  2. a) Authentication:

Execute an authentication protocol such as EAP (Extensible Authentication Protocol) for secure communication in mobile applications.

  • Adapt the protocol headers in C++ to contain an authentication mechanism.
  • Generate TCL scripts that mimic authentication processes when a mobile node starts communication.
  1. b) Encryption:

We can execute a simple encryption at the application layer or adjust the packet headers to contain encryption logic.

  • Expand the NS2 codebase to contain encryption methods such as AES (Advanced Encryption Standard) in the C++ protocol layers.
  • Mimic encoded communication by adding encryption/decryption routines in TCL script.
  1. c) Intrusion Detection System (IDS):

Implement IDS to identify malicious activities.

  • Execute an algorithm such as anomaly detection to observe network activities.
  • Compose code in C++ to identify unusual traffic patterns and generate alerts.
  • We can mimic attack scenarios such as DDoS (Distributed Denial of Service) and monitor how the IDS react.
  1. d) Firewall:

Execute a implement firewall that filters packets based on predefined rules.

  • Expand the packet processing logic in NS2 to permit or block packets according to source IP addresses or other characteristics.
  • Adapt the TCL script to mimic firewall rules.
  1. e) Data Integrity:

Execute Message Integrity Codes (MIC) to make sure data integrity.

  • Adapt the packet transmission logic in C++ to estimate and validate data integrity codes.
  • Mimic the scenarios in which packets might be altered with and monitor on how the system reacts.
  1. Code Modification in NS2:
  • Packet Headers: Adapt the packet.h file to add fields for encryption, authentication, or IDS alerts.
  • Routing Protocols: Adjust the C++ files for routing protocols such as AODV or DSR to contain security checks.
  • TCL Scripts: Compose simulation scripts to describe network topology, traffic sources, and movement patterns.
  1. Simulation and Testing:
  • Describe security test cases such as unauthorized access attempts, encrypted traffic transmission, or intrusion detection.
  • Execute simulations using NS2, capture the trace files, and measure the performance of the security mechanisms.
  1. Analyse Results:
  • Use the trace files to measure security performance such as how well the encryption works, detection rate of IDS, etc.
  • Evaluate network throughput, packet delivery ratios, and latency for key parameters.

Sample TCL Code Snippet:

# Create mobile nodes

set ns [new Simulator]

set topo [new Topography]

set god [create-god 5]

# Define mobile nodes

set node_(0) [$ns node]

set node_(1) [$ns node]

# Define application layer traffic with encryption (Pseudo-code)

$ns at 10.0 “$node_(0) send-encrypted-data $node_(1)”

This technique contains to adjusting NS2’s codebase in C++ for low-level security protocols and composing the TCL scripts to mimic the secure mobile application network.

In this presented replication, we clearly understood and gain knowledge about how to execute and enforce the mobile application security using ns2 tool that will help to secure the mobile application. If you have any query regarding the mobile application security we will provide it too.
