Secure Mobile VPN Implementation with IPsec on Android Phones

The project aims to develop a VPN using IPsec on Android phones for secure communication. It involves encryption, integrity checking, and authentication using pre-shared keys and digital signatures. The key exchange is performed using IKE-v2. Setting up the VPN involves the Android phone-to-Android phone configuration using StrongSwan 4.5 and related tools. Risks include mobile processing power limitations and the potential for exploits. Benefits include secure data communication and the development of sophisticated mobile apps. The project progress includes software integration on Android phones and a partial demo setup with the potential for advanced mobile applications.

  1. IPSecVPNon a Android Phone Group 1 AvinashBhashyam Axel Christiansen

  2. Group Project Description • Internet Protocol Security (IPsec) is a framework of open standards for ensuring private communication over the virtual public network. • The goal of the project is to Use IPsec to create a Virtual Private Network(VPN) on a Android phone.

  3. Tasks allocation • AvinashBhashyam • Research (50%) • Programing (75%) • Report (25%) • Axel Christiansen • Research (50%) • Programing (25%) • Report (75%)

  4. Technical Details • Confidentiality is provided by using Ipsec encryption over a VPN Network. • Integrity checking is to be provided by using the HMAC-MD5. • Authentication is provided by the pre-shared keys and Digital Signatures. • Reply protection and the access control are to provide by periodically changing the pre-shared keys. The key exchange can be performed using the IKE-v2 protocol.

  5. Technical Details (Cont.) • The VPN can be setup in the following manner: • Android Phone to Android Phone • This where the Calling Android Phone is the control for the VPN. • Software,: StrongSwan 4.5, Linux, Android 2.0 Emulator and Android SDK,. • C compiler. • Hardware : Basic Computer with network conative and Android Phone.

  6. IKEv2 Peer-to-Peer NAT-Traversal for IPsec Over VPN

  7. End-to-end VPN Usage Scenarios

  8. Risks and Benefits • Novel aspects of this project: • Setting up a IPsec VPN from mobile phones • Risks/challenges: • Processing power of the mobile is much lower than that of a traditional computer. • Flaws in algorithms,software or configuration setting can be exploited by attackers • Potential applications & benefits: • Data can be communicated securely over public networks. • Sophisticated Mobile Apps can be developed.

  9. Tasks Accomplished by Now • Software has been incorporated in to the android phone. • Demo has been somewhat setup.

  10. Conclusion • Successful implementation of the project has the potential to led to developing Sophisticated mobile applications. • Project may lead to a potential public application.

  11. Demo • A project Demo using Virtual Terminals and VPN gateway.
