← ScienceWhich risk increases during lossless data compression when entropy decreases toward zero thanks to carefully crafted weighting functions?
A)Catastrophic heap overflow event
B)Increased parallel processing efficiency
C)Vulnerability to dictionary attacks✓
D)Diminished data caching effectiveness
💡 Explanation
Reduced entropy means predictable patterns, because information gain from each bit is lower. Entropy-encoded compression now depends on publicly calculable functions; therefore, dictionary attacks work, rather than brute-force ones, because keyspaces are vastly smaller.
