WebApr 13, 2024 · Use a reliable source of entropy. Entropy is the measure of uncertainty or randomness in a system. The more entropy, the more unpredictable the random numbers. To generate secure random numbers ... WebTo search for keyword w, the client just sends a deterministic encryption of w to the server. This encryption of the keyword, d w = E n c K 1 D ( w), will serve as the token. Now all the server has to do is compare d w to all the deterministic encryptions in E D B. If d w is equal to any of them, the server follows the corresponding pointer and ...
