Cryptography Using Modified Fractional Fourier TransformKernel

Cryptographic Method Using Modified Fractional Fourier Transform Kernel

This technology is a cryptographic method, using at least one component of a modified fractional Fourier transform (FrFT) kernel, that enables an encrypted message header to act as an electronic signature. This method encrypts digital signals by the sequential action of a modified FrFT kernel. The encryptor key is a set of positive numbers controlling the phase, angle, exponent, FrFT kernel, and wavelet family. Decryption is achieved by reversing the operations.
