WebComputational hardness assumptions are of particular importance in cryptography. A major goal in cryptography is to create cryptographic primitives with provable security. In some cases, cryptographic protocols are found to have information theoretic security; the one-time pad is a common example. Webdard cryptographic hardness assumptions. Our results, therefore, indicate that perhaps a similar approach to cryptography (relying on computational hardness) holds promise for achieving com-putationally robust machine learning. On the reverse directions, we also show that the existence

WebAug 17, 2024 · Basing Cryptography on Structured Hardness. We aim to base a variety of cryptographic primitives on complexity theoretic assumptions.
