  1. Re:One Time Pad on Israeli Firm Claims Unbreakable Encryption · · Score: 1
    If you keep the cdrom, and someone takes it after you have been seending messages for a couple years, then all those messages could be decrypted.

    You can rig the cd-drives to destroy the bits as they are read from the cd, or you coud use harddisks and overwrite the bits (multiple times with random patterns) as they are used.

    There is of course alway a risk that the one time pad is somehow compromized during transfer or storage. One must have routines to avoid or at least detect it.

    Any cipher that relies on mathematics can not be proven secure. If you look up Gödel's Incompleteness Theorems, you'll see that in any axiomatic mathematical system there are propositions that cannot be proved or disproved within the axioms of the system. So if I propose that there does exist some (unspecified) mathimatical way to break that cipher, you won't be able to 100% conclusively _disprove_ it.

    You have misunderstood this theorem.

    Yes, any axiomatic system has sentences that can not be proven or disproven within the system. But if I prove a sentence I HAVE proven this sentence and disproven the negative of the sentence.

    Then neither the sentence or the negative is in the set of senteces that can neither be proven or disproven.

    So if I within a aximatic system find a prof of A and you propose a sentence B has the property B -> !A (from B follows the negative of A) I already have a prof of !B

    One of the basic rules of logic is:
    A & ( B->!A ) => !B

    Well if you are going to record the key on a cd and deliver it by hand (which you would have to do for each message, since it is a one time pad ) you might as well deliver the message your self.

    Two identical cdroms with random data woud be enough to to keep you chatting for years if you restrain yourself to text only messages.

    One time pads are cumbersome, but with todays storage capabilities no more so than old fashioned symetric key encryption, witch also requiers a secure channel ( i.e currier ) for key transfer.

    For the same reasoning OO programming is non-ideal.

    It is true that an OO program often will underperform compared to a well written C program doing the same task.

    The computer might be close to perfect (pentium bug anyone) but the programer is not.

    A well desinged OO program will shorten development time, ease cooperation between multiple programers/teams, reduse the amount off bugs in the program and ease mantainace.

    All of this is well worth the performance hit in many occasions.

    Maybe it's just me, but whenever it looks like a harddrive is about to die (funny noises, etc. or just getting old) we replace it before it does. Also, we back up critical information, often in more than once place. This sort of practice should, in thoery, prevent this from happening. These things are replacable.

    You are correct about data that are in active use. But what about the countless gigabytes of digital photos, articles, newstories, email (letters have been an enormusly value source for historians) and other digital documents that are rotting away on some CD-R, backup tape or other quickly degrading media.

  11. Re:Falun Gong are terrorists. on Falun Gong Hacks Chinese Satellite · · Score: 1
    I call upon the US and International bodies to come up with a clear, accurate, definition of what a terrorist is.

    Making a good definition of terrorism and terroists is not easy. I guess the goverments would want a very wide definition to give them more power to prosecute people who disagre with them and (some) people woud want a narrower definition to avoid being stamped as terrorist for trying to campaing for a cause (for example using civil disobedience).

    My intuision is that the differce between a terroist act and an act of war is in the intended target.

    If you target or treaten civilians you are a terrorist.

    So attacking a US warship would be an act of war, blowing up the twin towers was terrorism.

    There is offcource a lot of grey area in this definition. What if you target a "valid" target knowing a lot of civilians will be colateral damage? What if the enemy hides his military targets behind a shield of civilans? What if the civilans shield the targets of their free will? Are they still civilans? If a taliban succedes in killing the commander in chief of the US armed forces (the president)? Terrorist or war hero?

    So my defintion is not very usefull for any academic or legal use as it is to impresise, but i think it still contains the essence of the difference between a terrorist and a freedom fighter

    So, GPL does not protect the code from commercial use after all.

    The GPL was never intended to protect the code from commersial use.

    It was intendet to protect the GPL'ed code from being used in closed source and restrictive licenced products/projects.

    You can sell GPL'ed products all you want as long as you give the buyer the rights the GPL says you have to give to the buyer.

    Another thing is that the GPL make commercial use difficult if you are making an "of the shelf" product because it requiers you to give away the source code and the right to redistribute to all buyers.

    If you are making customized applications for spesific customers using GPL'ed projects as a starting point can save you lots of work and the requirements of the GPL can even be used as a selling point; "you get the source so if I go broke you can get another company to do any furhter developments needed".
