WebLattice-Based Cryptography. Lattice-based cryptography is one of the leading candidates for post-quantum cryptography. A major focus of my work has been on constructing new cryptographic primitives such as zero-knowledge proof systems, watermarking, and more, from standard lattice assumptions. Webside effect that yields longer cryptographic signatures and watermarks is produced. Such an obstacle discourages [1] from being a robust watermarking method in resisting geo-metric attacks [6, 10]. On the other hand, it can also be observed that the ex-isting methods that were proposed to deal with the proto-
