Signcryption from trapdoor permutation
WebA trapdoor one-way function or trapdoor permutation is a special kind of one-way function. Such a function is hard to invert unless some secret information, called the trapdoor, is known. A one-way permutation is a one-way function that is also a permutation — that is, a one-way function that is both injective and surjective. WebThe notion of deniable encryption (DE) was introduced to achieve secret communications in situations of coercion or bribery. Generally, it allows a user to open the same ciphertext into multiple different messages. After the initial constructions, numerous DE …
