yasno. Az sqm vizhdal spekulacii, che v dizayna na DES ima narochno
ostaveni trapdoors. V edna sravnitelno stara kniga, Cryptography:
Theory and Practice (Douglas Stinson, 1995, CRC Press) se kazva
(citat, pp 82)
The S-boxes, being the only non-linear component of the cryptosystem,
are vital to its security. ......
However, the design criteria of the S-boxes are not completely known.
Several people have suggested that the S-boxes might contain hidden
"trapdoors" which would allow the NSA to decrypt messages while
maintaining that DES is secure.
Kato kaza, che DES imal bug, si pomislih dali nyamash predvid neshto
v tozi smisql, otkrito naskoro.
