Web11 de jun. de 2024 · Functional Encryption (FE) expands traditional public-key encryption in two different ways: it supports fine-grained access control and allows learning a function of the encrypted data. In this paper, we review all FE classes, describing their functionalities and main characteristics. In particular, we mention several schemes for each class, … Web10 de nov. de 2024 · The functional encryption scheme designed using the lattice can realize fine-grained encryption and it can resist quantum attacks. Unfortunately, the sizes of the keys and ciphertexts in cryptographic applications based on learning with errors are large, which makes the algorithm inefficient. Therefore, we construct a functional … Webciphertext attribute expressed by x satisfies the formula expressed by v.Although Bob knows sk v and v, Bob has no idea which attribute x is embedded in ct x except that the ciphertext attribute satisfies the formula, i.e., v·x = 0, if the fully attribute-hiding security is achieved. On the other hand, Bob may obtain some additional information on the … duval county schools ese
