Data Encryption Method Using Discrete Fractional Hadamard Transformation |
摘要 |
A data encryption method using discrete fractional Hadamard transformation includes the steps of: providing a set of data; processing the data with discrete fractional Hadamard transformation to generate at least one Hadamard matrix, the Hadamard matrix having eigen vectors corresponding to eigen values; selecting order parameters from order vectors of the Hadamard matrix; designating the order parameters as a private key in data encryption. In an embodiment, a set of integers is designated to define numerators and denominators of fractions which represent the eigen values of the Hadamard matrix.
