Injective continuous function

WebbLossy trapdoor functions (LTFs) were first introduced by Peikert and Waters (STOC’08). Since their introduction, lossy trapdoor functions have found numerous applications. They can be used as tools to construct important cryptographic primitives such as injective one-way trapdoor functions, chosen-ciphertext-secure public key encryptions, deterministic … Webb4 aug. 2024 · Proving it is not hard usually, for example, any continuous injective function from a compact space to a Haudorff space is necessarily a homeomorphism to its …
