I'm planning to do a mobile VPN application for my BSc final year project. I hav a doubt wheather this can be possible to do so.

The concept of this application is mentioned below

1. GPRS is using as transmission medium
2. Encryption method is using to secure data. (Need to know wheather can be done using phone's processor)
3. Server side application is using for interconnect nodes (phones)

Please reply with any ideas

Most definitely can be done, I loaded an IDE for a popular mobile device and it had all three of these already coded in the java api for use directly by the programmer. I would like to do some of the preliminary work with you for your project.

Thank you very much Jordan. I appreciate your helpfulness

Also I need to clarify whether it is possible to implement such application without going into Client-Server architecture.
Also I'm willing to embed an encryption mechanism for a proposed application. Is it possible to do data encryption with phone's processor?

Thanks!!!

I'm pretty sure that J2ME comes with a set of encryption services.

I'd be even surer if I wasn't too lazy to check the available JavaDocs.

Sorry, I have been very busy - I am a senior assistant on a large project and have to attend that duty first. Tim Holloway knows enough about the subject that you may rely on his advice when I am not present and I will attend to any details I wish to make different from his advice at the time of my return. { hey, jr'rs: cool or what ? }

First delete your duplicate posts, I understand your eagerness.

  • 1.   Also I need to clarify whether it is possible to implement such application without going into Client-Server architecture. Client-Server is a way of thinking, and is not the only way to do it. We will receive much criticisim for this thought. Tell them to post those comments in Meaningless Drivel where they belong. Client-Server has a rich history and will serve us well in some places. We will use the Code We Can Understand architecture.
  • 2.   Also I'm willing to embed an encryption mechanism for a proposed application. Is it possible to do data encryption with phone's processor? See below:

  • That was taken from EricGiguere.com > Eric's J2ME Pages > J2ME Security at

    J2ME Security

    which you should read immediately. This is actually what Tim is saying, you should look up some of this stuff yourself. I need to know what you have studied already for the BSc final year project - big impact on how I present my words to you. North American Street English is my native speak but there is no native speak for computer science and the program vary widely from one time and place to another.

    Cryptography is extremely hard to tell apart from useless beginner blunders and we will have plenty of tools in the processor, as you call it.

    Study with great dilligence but no expectations: Learning Path: MIDP Application Security Learning Path: MIDP Application Security which Gathers resources related to application security in general as well as information specific to MIDP.

    The phone has a reasonbly powerful processor and we need to target any of the Open Handset Alliance members:

    ( I will send you a private message with the full list )

    This effort is far more involved than a one-semester final project for a computer-science course. I can make suggestions on how to package the effort for you class. To do this I ( or Tim ) need some idea of how your courses have progressed to date.

    Not a problem, have been trying hard to find anyone who is sufficiently interested. I give you your first assignment: Many customers will want to access some sort of web address, it may be that our application does not use this - I want to see how you go about solving the challenge.

    Thus: provide code to look for: "http://" in a string typed in by the user. There are many ways to approach this, I want to see how you go to work on this so that I know how to guage my comments and replies to you.
