Description: Fuzzy cryptography is a branch of cryptography that uses fuzzy logic principles to develop cryptographic systems capable of handling the uncertainty and imprecision inherent in data. Unlike traditional cryptography, which relies on the certainty and precision of data, fuzzy cryptography allows for the representation of information in terms of degrees of truth, making it particularly useful in contexts where information may be incomplete or ambiguous. This technique is based on fuzzy set theory, introduced by Lotfi Zadeh in 1965, and is applied in creating algorithms that can adapt to variations in input data. The main characteristics of fuzzy cryptography include its ability to provide security in environments where data may be noisy or imprecise, as well as its flexibility to adjust to different security levels according to user needs. In an increasingly interconnected world filled with data, fuzzy cryptography presents an innovative solution for protecting sensitive information, ensuring that even in situations of uncertainty, the confidentiality and integrity of data are maintained.
