Webstudied how to build watermarkable families of PRFs from weaker assumptions such as lattice-based assumptions [KW17,KW19] or CCA-secure encryption [QWZ18]. Watermarking public-key primitives. Existing constructions of software watermarking from standard cryptographic assumptions all focus on watermarking symmetric-key primitives, notably, WebThe mission of theoretical cryptography is to define and construct provably secure cryptographic protocols and schemes. Without proofs of security, cryptographic …

This unpredictability can be measured in terms of entropy, which the NIST SP 800-90 series measures using min-entropy. A full-entropy bitstring has an amount of entropy equal to its length. Full-entropy bitstrings are important for … WebConcrete assumptions include the universal one-way function assumption [ Gol01 ], 2 the as- sumption that Goldreich’s expander-based function is one-way [ Gol11 ], the Factoring and RSA incorporation fee deductible
