Dirichlet Convolution Cryptography
Noumerica develops cryptographic methods based on nonlocal arithmetic structure, particularly Dirichlet Convolution Modulo p (DCM). Rather than relying only on local substitutions and repeated mixing, DCM uses multiplicative structure to propagate information and randomness across encrypted data.
Fresh salting and nonlocal mixing give rise to information-theoretic masking properties established in Noumerica’s current research. The same algebraic structure also allows cryptographic transformations and keys to compose naturally.
