This is a list of some of the most common ones, and some cryptographic protocols that use them. Given a composite number , and in particular one which is the product of two large primes , the integer factorization problem is to find and (more generally, find primes such that ). It is a major open problem to find an algorithm for integer factorization that runs in time polynomial in the siz…

Cryptographic Assumptions: A Position Paper - IACR

WebJan 1, 2009 · A remarkable feature of lattice-based cryptographic functions is that they can be proved secure (that is, hard to break on the average) based on the assumption that the underlying lattice problems are computationally hard in the worst-case. WebWe propose a cryptographic obfuscation scheme for smart contracts based on existing blockchain mechanisms, standard cryptographic assumptions, and witness encryption. In the proposed scheme, an obfuscated smart contract does not reveal its algorithm and hardcoded secrets and preserves encrypted states. Any user can provide it with encrypted ...
