Umro sam od smeha. Ali ujedno veoma zanimljiva tema.
samo neka stave Maxtor-ov hard disk
on ce automatski da napravi self-distruct sam od sebe ,pre ili kasnije O0Ma druga stvar mene muči. Gledam onaj kako-da na koji je ubutio foxbunny, i vidim da enkripcija može biti i zabranjena zakonom. Zna li neko kako stoje stvari s tim kod nas, i da li je negde zaista protivzakonita. Mislim pri tom na sledeće:
As the fear of governments of cryptography being employed by criminal circles has produced some strange regulations concerning the use of strong encryption, it cannot be over-emphasized how important it is to know the law in your own country:
1. Am I allowed to use strong cryptography?
2. Am I allowed to use a particular cipher algorithm either for private or commercial use? Do I have to pay licence fees?
3. Am I allowed to participate in the development of software that contains strong cryptography?Ne znam tačno ni da li je to regulisano. Ali u svakom slučaju, poenta je da moraš predati šifre ako pronađu enkriptovanu particiju ili fajl. Onaj truecrypt te lišava te potrebe dok ne dokažu na neki drugi način da si ga zapravo koristio na svojim podacima. Vrlo fina fora.
Use in cryptography
In cryptography, deniable encryption may be used to describe steganographic techniques, where the very existence of an encrypted file or message is deniable in the sense that an adversary cannot prove that an encrypted message exists.
Some systems take this further, such as MaruTukku and (to a lesser extent) FreeOTFE/TrueCrypt which nest encrypted data. The owner of the encrypted data may reveal one or more keys to decrypt certain information from it, and then deny that more keys exist, a statement which cannot be disproven without knowledge of all encryption keys involved. The existence of “hidden” data within the overtly encrypted data is then deniable in the sense that it cannot be proven to exist.
http://en.wikipedia.org/wiki/Deniable_encryption
In cryptography, deniable encryption allows an encrypted message to be decrypted to different sensible plaintexts, depending on the key used, or otherwise makes it impossible to prove the existence of the real message without the proper encryption key. This allows the sender to have plausible deniability if compelled to give up his or her encryption key. The notion of “deniable encryption” was introduced by Julian Assange & Ralf Wiennmann in the Rubberhose filesystem[1] and explored in detail in a paper by Ran Canetti, Cynthia Dwork, Moni Naor, and Rafail Ostrovsky[2] in 1996.
pre nekog vremena, odavno u stvari,nosio sam flopi kod druga ,nesto smo snimali
ali mi je izgleda njegov drajv unistio flopi disk
i tako je sedeo flopi sa onim bad-sektorima dok nisam pogledao neko uputstvo za programiranje
disketne jedinice,i nesto sam ga bio skenirao (u linux-u) odredivsi otprilike
gde su losi sektori,a zatim pomocu specijalne te komande za programiranje je
izprogramiran da cita samo sa jedne strane flopija ,i posto su bili losi sektori
umountovao sam ga negde od sredine(zaboravio sam tacne komande trenutno)
i stavio sam ext2 fajl sistem,dobivsi korisnu povrsinu od ~200Kbajta
i tu sam iskopirao jednu sliku,ono za probu
ali ovo bi bio zanimljiv nacin za skrivanje podataka jer
1. prvo treba da se reprogramira privremeno floppy drajv
2. treba da se umountuje od tacno odredjenog mesta
(doduse nije mi palo na pamet da upotrebim enkriptciju)Pa fora je bila u tome da se burga plasi zakona (ako, i treba!). U tom slucaju mu treba enkripcija cije postojanje moze da porice bez mogucnosti da tuzioci otkriju laz. 😉 Sa tvojim metodom bi se kad-tad otkrilo kada budu imali raw pristup floppyju.
Pa, rekao bih da je TrueCrypt rešenje.
