Demonstrates a combination of 2D-Discrete Wavelet Transform (2D-DWT) with post-quantum cryptographic techniques, including a simulated version of the Falcon signature algorithm, for securing images.

Implements a multi-level approach to image encryption and signing using post-quantum cryptographic techniques, with a focus on the FALCON (Fast-Fourier Lattice-based Compact Signatures over NTRU) algorithm for digital signatures.
