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. WebApr 13, 2024 · Most device-independent protocols are based on the violation of bipartite Bell inequalities (e.g. the CHSH inequality). In our work, we show that multipartite nonlocal correlations, testified by the violation of multipartite Bell inequalities, enable the certification of more secret randomness from the outcomes of one or two parties.

WebNov 6, 2024 · In cryptography, the term random means unpredictable. That is, a process for generating random bits is secure if an attacker is unable to predict the next bit with greater than 50% accuracy (in other words, no better than random chance). We can obtain randomness that is unpredictable using one of two approaches.
