What? That's what you call a progress???
This is exactly what was happening to me today when I met my advisor/supervisor. Hi hi hi…
And he gave a bunch of questions and a long to-do-list, result in an expanding mind maps of mine! Aaaaaaaaa!!!!

Some of my favorites book arrived today. One of the is this book
But the funny thing is, it has different cover with those I found on the web:
Is it because they’re from different publishers, or there are different versions, I will find out π
Ready to enjoy the book… (the piles is getting higher, adding more distractions for me, hi hi hi…)
Ah … those distractions. I think you should work on your stuff first. Show me your progress. Minor progress is okay, as long as it is progressing.
Then, you can read a book for your reward.
As for that book, I read it already but wouldn’t mind re-reading it again.
tulisin short summary-nya di sini dong.
biar bisa ikutan baca, dikit-dikit π
Enjoy the books but dont forget pak BR comment π work on progress first…
BR: but what if i need some βdistractionsβ to make some progress, sir? hi hi. i will take the advice and will stay away from the (new) books. but let me at least finish βthe cuckooβs eggβ, hi hi hi *blink blink*
Kusprasapta: ok π campur2x sama coding tapi ya π
Rindu: yes, trying hard to make some progress here π
Forgot to inform that my academic supervisor #1 adviced me to postpone the quals until I’m ready with the “hands-on experience” (in this case will be coding). He suggested me to stop reading papers and start to implement the theory has been gathered.
So I will stop those “endless paper-hunting” activity for a while and focusing on building a small cryptosystem and make it work!
Chika … who is “He”? π
Dr. Ir. Kuspriyanto, beliau promotor utama saya π
i totally agree with your academic supervisor #1 π
reduce reading paper (don’t stop :)), focus and build a small system.
yes, but i don’t feel like reading papers right now, so much into the coding π
but i will read some papers and search some updates about the latest, maybe next week
good luck!
I agree that we need to do some hand-on experience to get more insight about a theory, swinging between generalization/theoritic thinking to spesific observation/experiment and vice versa
Klo kangmas ku pasti nyuruh baca yaaa kwakwkakwakwk. Dasar memang dianya yg gila baca. Beda ma otak kita, dia baca langsung bisa membayangkan dan ngerti, kita baca…praktek dulu baru ngerti
@intan: thx, partner :* we haven’t discussed about our project for quite a long time π
@budi sulis: exactly. i’m looking for experiences and insights to comprehend the theory. but i often find difficulties in switching between those two domains (theoritical vs experiment). how do you deal with that?
@luche: hey! so nice to have you here! kangmasmu belum bales email pertanyaan dari aku, sibuk banget dianya!
iya bisanya komen di sini, di multiply musti bikin dulu maleeessss
Have been doing some coding on large integers for the last couple of weeks.
The integers are represented in a half of 32 bytes words.
So far the program has been verified for the addition, substraction, multiplication and division operations.
Functions for converting ascii to large integer or vice versa have also been built and verified.
Next step will be developing some functions for basic number theory like GCD, modular arithmetic, Fermat’s theorem, finite fields and generators.
Still a long way to go, even for a simple cryptosystem to convert a word into a point in elliptic curve.
Salut … no future comment !
trims Rindu, belum apa 2x, ini, kerjaannya masih banyak!!! π
dalam komputer arsitektur Intel IA32, bilangan integer memiliki representasi sebanyak 4 byte (32 bit).
kalau saya lihat dalam code yang dibuat, integer-nya memiliki representasi sebanyak ‘half of 32 bytes words’.
jadi boleh dibilang, representasi integernya sebanyak 0.5 * 32 * 8 bit = 128 bit, atau 4 kali lebih besar dari representasi biasa.
tentu ini ada trik-nya ya?
ya ya ya ya… nge-trik-nya aja meni butuh waktu, ampun!
I will just scribble notes here about what I got from the regular discussion today:
Any progress?
yes, but not much. still working on the coding. hopefully nextweek there will be some significant progress
I’m now building some simple codes for converting plain text character to a point on an elliptic curve.
Here’s how I’m gonna do it, based on Mike Rosing’s hints:
To get the x value back, just mask off the extra bits to recover the raw data.
Going to give a presentation at the Math Dept. tomorrow. Talking about cryptography and ECC and ECDLP. Will avoid explaining about those math equations, otherwise the students will eat me alive, hi hi hi
Wish me luck π
Good luck mbak. Nice to find your blog. It is really a niche blog with cryptography inside. Best regards from Brussels
hello aris, thx for dropping by.
what an impressive blog about foreign affairs of yours!
good luck with your presentation at the math dept.
but i don’t think you can avoid math π
wait for result of the presentation.
post immediately!
Good Luck… so, how the result of yesterday presentation dear? report yak !!
@kusprasapta: i only avoid math when i’m presenting in front of mathematicians π
@rindu: thx for asking, but i don’t think i did it well π¦ kacow!
you did it well!! they are more motivated by you than by my speech for a whole semester!
infact, in front of mathematicians, you have to describe engineering things with the language of mathematics π
so proud that you have a gut to do presentation in front of science people. because i’m not! π
just want to tell you my new ‘mathematical side’ blog π
Well done! We’re all proud of you. π
@intan: are you sure? REALLY??? they seemed like they were not interested at ALL!!!
btw, i already add you “mathematical side” blog rss feed and link to this blog π
@kusprasapta: i think i failed to deliver the message using their language :((
this posting is so true http://rahard.wordpress.com/2008/05/14/delivering-the-message/
@BR: thx π you’re always inspiring me
After spending hours googling and reading some pdf and presentation files, I still cannot find the correlation between the term “diffusion” with ECC.
For now I do really think that the term “diffusion” is only for symmetric-key system.
Will find out more about it later. Hmmm….
To make sure that your cryptosystem is secure, then you have to do cryptanalysis.
The known attacks for ECC are:
Next step will be to choose which attacks to be used for measuring the level of security of ECC.
Diffusion means many bits of the plaintext (possibly all) affect each bit of the ciphertext.
Confusion means there is a low statistical bias of bits in theΒ ciphertext.
Question: the diffusion behaviour for ECC in encryption process?

Hey … I didn’t do that. ha ha ha. Yes, I always ask for progress. So, is there any progress?
chikaradirghsa 11:30 pm on May 30, 2008 Permalink |
yes there’s some progress. but they’re still in my term, not yet in your term, sir π next week hopefully there will be some progress comply with your request π

You better have some results next week! :p
Rindu 12:36 pm on June 2, 2008 Permalink |
talk about progress.. for me it means ” from step to result” π

Progress … ? What progress, Sir?
… in harmonia … progressio! (sounds like a spell) :p
