Cryptographic assumptions
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. 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.

There are many cryptographic hardness assumptions in use. 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… WebThe decisional Diffie–Hellman (DDH) assumption is a computational hardness assumption about a certain problem involving discrete logarithms in cyclic groups. It is used as the basis to prove the security of many cryptographic protocols, most notably the ElGamal and Cramer–Shoup cryptosystems .
WebApr 14, 2024 · The security strength of a random number generator depends on the unpredictability of its outputs. This unpredictability can be measured in terms of entropy, … WebAug 25, 2024 · The hardness assumption one works with (roughly there are LWE-type, LWR-type, SIS-type, and NTRU-type assumptions, although defined appropriately one can even view LWR-type assumptions as being a special case of LWE-type assumptions with non-i.i.d. noise). One can get a diversity of schemes.
