Cryptographic hardness assumptions

Computational 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. See more In computational complexity theory, a computational hardness assumption is the hypothesis that a particular problem cannot be solved efficiently (where efficiently typically means "in polynomial time"). … See more 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. Integer factorization Given a composite number $${\displaystyle n}$$, … See more Computer scientists have different ways of assessing which hardness assumptions are more reliable. Strength of hardness assumptions We say that assumption $${\displaystyle A}$$ is stronger than assumption $${\displaystyle B}$$ See more As well as their cryptographic applications, hardness assumptions are used in computational complexity theory to provide evidence for mathematical statements that are difficult to prove unconditionally. In these applications, one proves that the … See more • Security level See more WebHardness of learning from cryptographic assumptions. Among several previous works [34, 35] which leverage cryptographic assumptions to establish hardness of improper learning, most relevant to our results is the seminal work of Klivans and Sherstov [36] whose hardness results are also based on SVP.

Assume sub-exponential security of the following assumptions: WebAt the center of this new type of quantum cryptography are cryptographic hardness assumptions. Certain problems, such as factoring numbers, are believed to be difficult for classical computers but not for quantum computers. Other problems, such as finding the shortest vector in a lattice, are believed to be hard for both types of computers.

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 . WebThe Decision Linear (DLIN) assumption is a computational hardness assumption used in elliptic curve cryptography.In particular, the DLIN assumption is useful in settings where the decisional Diffie–Hellman assumption does not hold (as is often the case in pairing-based cryptography).The Decision Linear assumption was introduced by Boneh, Boyen, and …
