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. WebOptimal signcryption from any trapdoor permutation.

In the mathematical and computer science field of cryptography, a group of three numbers ( x, y, z) is said to be a claw of two permutations f0 and f1 if. f0 ( x) = f1 ( y) = z. A pair of permutations f0 and f1 are said to be claw-free if there is no efficient algorithm for computing a claw. fishing vancouver bc

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.

Webthat signcryption can be built from ordinary signature and encryption, but will be ineﬃcient unless the latter are eﬃciently implemented. In practice, eﬃcient signature and encryption schemes, such as OAEP [5], OAEP+ [13], PSS-R [6], are built from trapdoor permutations, 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.
