WebMay 2, 1999 · We propose a new trapdoor mechanism and derive from this technique three encryption schemes : a trapdoor permutation and two homomorphic probabilistic encryption schemes computationally comparable to RSA. Our cryptosystems, based on usual modular arithmetics, are provably secure under appropriate assumptions in the standard model. Webgeneration algorithm, and used Chameleon hash function to remove the trapdoor and construct a challenge tuple in the proof. Compared with the schemes in the random oracle model at that time, Yan’s signcryption algorithm is more efficien-t. In 2014, Lu et al [Lu et al., 2014] gave a lattice-based signcryption scheme,
Provable image encryption scheme via trapdoor permutation
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.

An anonymous trapdoor permutation or a repeated variant of the padding PSEP (as the solutions proposed in [7]) could be used to solve this problem but this would decrease the scheme’s efficiency.
