Configurable radix-4 NTT hardware optimization and implementation for lattice-based cryptography
In response to the complex polynomial multiplication issue in lattice-based cryptography algorithms optimized with number theoretic transform (NTT), as well as the demand for NTT designs catering to multiple application scenarios, a configurable radix-4 NTT hardware architecture for lattice-based cryptography was proposed.By analyzing the radix-4 N
