WebApr 16, 2024 · On a high level, the lemma says that if a long string \(X \in \{0,1\}^k\) has high min-entropy (e.g., because it was chosen uniformly at random and the adversary could only remember \(m \ll k\) bits of information about it, in which case X denotes the conditional distribution), then many individual bits X[i] of X must have non-trivial min-entropy. WebOct 20, 2024 · Entropy is a measure of how unpredictable a complex system is: more entropy yields greater uniqueness. For high security, significant entropy must be used to generate your digital wallet seed phrase. Numbers with high entropy can be generated either by computers or manually. Vault12 can produce high-quality, high-entropy seed phrases …
