Witryna21 lut 2024 · Preimage Sampling is a fundamental process in lattice-based cryptography whose performance directly affects the one of the cryptographic mechanisms that rely on it. In 2012, Micciancio and Peikert proposed a new way of generating trapdoors (and an associated preimage sampling procedure) with very interesting features. WitrynaThe trapdoor-independent preimage sampling algo-rithm allows [GPV08] to securely build a hash-and-sign signature as follows. Let the matrix A be the public veriﬁcation key, the trapdoor of A be the secret signing key. To sign a message m, ﬁrst hash it to a vector y, then use the trapdoor to sample a short preimage xas the signature. The …
