Simplistic pseudo random number generators

WebbDescription. Standard pseudo-random number generators cannot withstand cryptographic attacks. Insecure randomness errors occur when a function that can produce predictable values is used as a source of randomness in security-sensitive context. Computers are deterministic machines, and as such are unable to produce true randomness. Webb15 apr. 2024 · Proof-carrying data (PCD) [] is a powerful cryptographic primitive that allows mutually distrustful parties to perform distributed computation in an efficiently verifiable manner.The notion of PCD generalizes incrementally-verifiable computation (IVC) [] and has recently found exciting applications in enforcing language semantics [], verifiable …
