Papyrus 5.0
Hi everyone,
I had this wonderful seminar called Papyus 5.0 at my college which was awesome. It was live streamed on YouTube and apparently I had a very large invisible audience though I had a limited visible audience at the college itself because my speech was just before the lunch break. It was exhausting even for me. It was my first paper presentation and first live presentation. I always wanted such kind of thing and this is awesome. I know it sounds gross but for me this was when I have literally overcome my stage fear and I spoke quite frankly. It differs heavily from the speech I prepared. I know I stuttered a bit but it is way better compared to my previous experiences. I literally threw up on stage the last time. The time constraint and thirst in this hot weather choked me but all in all I'm proud of my achievement.
Video: That's me presenting my paper.
Yeah, about that green thing and that number. It is actually called Mobius strip. The number is the patent number which gives an encryption algorithm detail. The encryption is used in mobile systems and I was about to tell the hazards in mobile security. I wish I had 2 more minutes. Anyways, it was good all in all.
I'll give you the link to original YouTube video here.
Click here to see the original YouTube video : 3:16:28
Thankyou
The "Power"point
Hello one and all,
Yeah, the video I uploaded wasn't showing neither me nor the presentation properly. So I thought I'd put the powerpoint slides. Don't worry, it's self explanatory.
ikee iphone virus
Yeah, I promised to upload the virus that created havoc in the iphone but was debugged even before it became a news.
I wonder why iphone is famous... yupp! Customer service. Despite its deep vulnerability, the igeniuses are debugging these things everyday. The customer satisfaction is therefore more prominent and famous than its lack of security. Linux has been better in security and hence the Linux movement. I couldn't say that on stage. damn the two minutes. I should have probably skipped introduction and palmOS. Mistakes happen. don't they?

The making of Mobile OS
Here are some links that can take you through my research during this incredible journey... It is related to both security and OS. Actually, more of security than OS. Now, come to think of it, I should have presented the paper only on security. Damn, Santosh... golden opportunity went in vain.
The link below is the explanation of Diffie hellman encrytion which was conclusion of my speech but unfortunately the judge "buzzed" a ring.
At the second half of video, you can see Diffie Hellman algorithm
Do you know how the innocent information you use can go in these complex algorithms and sometimes be clever than you? The link below shows one astonishing fact. Thanks to vSauce.
Frequency of our tech use and consequences.
I was speaking about NSA spying on people. This video teaches the "jurisdiction" of spying. It's awesome.
NSA is watching you.
I never included this in my speech but this was worth telling. Just check this one out.
James lyne - Everyday cyber crime.
This was very enlightening on Symbian in a very simple manner.
Research on Symbian
The link below is a very good paper on survivable mobile technology and worth reading.
Research on Mobile Security
Download the following book to understand Symbian better.
Symbian OS Internals: Real-time Kernel Programming by Jane Sales ISBN: 978-0-470-02524-6
Now I see why I took three slides for symbian. I did more work on Symbian tech, reading the book above for nearly five days killed the time. I hate myself.
SSS: Slideshow on Symbian Security
I found these in study somewhere online. I couldn't find the links because I didn't bookmark and I have security consciousness to delete my web history daily.
1. Android by 2012, A study on present and future of Google's Android By Dotcom Infoway
2. Open Source OS - The Future for Mobile? By Juniper Research.
All my works are totally inspired from TED talks. This is what future is...
Ted talks
The following was not much useful for speech but was very good in writing paper.

Cabir virus.
This is the source code of Cabir virus by name Caribe.A
I recommend the user discretion to try this on their (if present) symbian systems. I don't have one.
Also since this was found on internet at the link displayed below and I couldn't check this one myself,
I am not sure this is original virus or edited to make it less harmful. So user discretion adviced.
It looks worst abuse of c language and I'm guessing high level of obfuscation.
All this will be cleared once you test the stuff. Anybody can report their observations on this code.

Valentine's Day
I am so annoyed by people celebrating Valentine's day. They lick each other and my friends are buying unnecessary gifts to their girl friends. I have a girl in my mind but my love story broke very recently... This is annoying, right? So I came up with this video to settle the score. The thing which you call a heart is nothing but a blood pumper. Think with the brain! Technically, that's where your soul lies.
