Signcryption from trapdoor permutation
Did you know?
WebA highly practical parallel signcryption scheme named PLSC from trapdoor permutations (TDPs for short) was built to perform long messages directly. The new scheme follows … Web4.1 Using trapdoor permutations for signatures As in the case of public key encryption, there is a naive way of using trapdoor permutations to do the signing which is not secure. The idea is to use the public permutation ˇfor the public job of veri cation, and keep the private trapdoor permutation ˇ 1 for the private task of signing.
WebThus, given that practical schemes are anyway built from trapdoor permutations, it is natural to have highly optimized direct signcryption constructions from trapdoor permutations (in … Websigncryption. The new method, which we call Padding-based Parallel Signcryption (PbPS), builds an effi-cient signcryption scheme from any family of trapdoor permutations, such as RSA. Each user Ugenerates a single public/secret key pair fU=f 1 U used for both sending and receiving the data. To signcrypt a message

A trapdoor permutation is a bijection (1-1 and onto function) that is easy to compute for everyone, yet is hard to invert unless given special additional information, called the “trapdoor”.
