Sensitivity
With DSA, the entropy, secrecy and uniqueness of the random signature value k is critical. It is so critical that violating any one of those three requirements can reveal your entire private key to an attacker. Using the same value twice (even while keeping k secret), using a predictable value, or leaking even a few bits of k in each of several signatures, is enough to break DSA.

Famous quotes containing the word sensitivity:
“The vanity of men, a constant insult to women, is also the ground for the implicit feminine claim of superior sensitivity and morality.”
—Patricia Meyer Spacks (b. 1929)
“The sensitivity of men to small matters, and their indifference to great ones, indicates a strange inversion.”
