Similar to TDP-based signature and encryption … 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,

WebTrapdoor Permutation ¶. 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”. The public key is essentially the function description and the private key is the trapdoor. WebThe videos cover two families of public key encryption systems: one based on trapdoor functions (RSA in particular) and the other based on the Diffie-Hellman protocol. We … WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present a new, elegant composition method for joint signature and encryption, also referred to as signcryption.

WebThe contribution of this paper has two folds. In the first fold, we propose a generic construction of sequential aggregate signatures from families of certificated trapdoor one-way permutations. We show that our construction is provably secure in the random oracle model assuming that the underlying homomorphic permutations are trapdoor one-way. WebFeb 15, 2010 · Signcryption, introduced by Zheng ... The technique they proposed is similar to the encoding method of OAEP [5] and RSA is used as the underlying one-way trapdoor permutation.

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.

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. fish fongWebApr 1, 2024 · With the proliferation of cloud computing, data owners can outsource the spatial data from IoT devices to a cloud server to enjoy the pay-as-you-go storage resources and location-based services. fish fondantWebA highly practical parallel signcryption scheme named PLSC from trapdoor permutations (TDPs for short) was built to perform long messages directly.
