What is "basic cryptography"

WebIn cryptography, entropy is used to produce random numbers, which in turn are used to produce security keys to protect data while it’s in storage or in transit. The greater the quality of random number generation (RNG), the greater the quality of random keys produced, and thus the higher the security value of the key. WebThe higher the entropy is, the higher possibilities there are. The main problem with low entropy is that the random number generator will have less different possible states to switch over, therefore it will begin to repeat itself. The main way to detect such issue is to try to detect such repetition. popular hash programs

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.

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.
