Cryptographic hardness assumptions
WebWhen devising cryptographic protocols, one hopes to be able to prove security using the weakest possible assumptions. This is a list of some of the most common cryptographic … WebApr 14, 2024 · Full-entropy bitstrings are important for cryptographic applications because they have ideal randomness properties and may be used for any cryptographic purpose. Due to the difficulty of generating and testing full-entropy bitstrings, the NIST SP 800-90 series assumes that a bitstring has full entropy if the amount of entropy per bit is at ...

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, …
WebModern cryptosystems are invariably based on an assumption that some problem is hard. In Chapters 3 and 4, for example, we saw that private-key cryptography-both encryption …

We aim to base a variety of cryptographic primitives on complexity theoretic assumptions. We focus on the assumption that there exist highly structured problems --- admitting so called "zero-knowledge" protocols --- that are nevertheless hard to compute. Most of modern cryptography is based on the ... inatel eadWebAug 5, 2024 · Hardness assumption: Quantum-resistant ABE scheme is hard in the quantum computational model, primarily derived from fundamental lattice-based problems, including the shortest vector problem (SVP) and closest vector problem (CVP). inatel foundationWebAt 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. inches in a furlongWebdard cryptographic hardness assumptions.
