Given kn2000 , might be in 2000 ? If kn = in, then k→i (-2), n→n (0) not consistent. Let’s check ly again: if ly = of (common): l (12) → o (15) = +3, y (25) → f (6) = 25+3=28 mod 26=2→b? No, that's wrong. Given the complexity, I suspect it's a Caesar shift of +5 (decrypt by -5):
Test ly (l=12, y=25) decrypt -5: 12-5=7→h, 25-5=20→u → hu not common. Given the year 2000 and the phrase "useful paper", maybe it's a simple shift of ? Try first word thmyl : t(20)-7=13→n, h(8)-7=1→b, m(13)-7=6→g, y(25)-7=18→s, l(12)-7=5→f → nbgsf — not English. I think the most common quick cipher in such puzzles is ROT13 , but ROT13 on thmyl = guzly , not obvious. thmyl brnamj zf awrj ly alkybwrd kn2000
So gsnbo yimznq not promising. thmyl reversed = lymht no. Step 9: Check common cipher — perhaps each letter shifted by position (progressive Caesar)? Given kn2000 , might be in 2000
thmyl → g s n b o? Let's do systematically: t (20) ↔ g (7) h (8) ↔ s (19) m (13) ↔ n (14) y (25) ↔ b (2) l (12) ↔ o (15) So thmyl → gsnbo (not English). No, that's wrong
That doesn't look right either. Given the format, it's more likely a or similar. But without quick success, the most plausible intended plaintext is something like: "useful paper: submit your work by November 2000" or "useful paper: final draft for review by 2000" But since I can't decode it in one go, I'd need more time or a known key.
