WebbIn the paper, we propose the first proxy re-encryption scheme based on the hard worst-case lattice problems. Our scheme has many useful properties as follows: Unidirectional, collusion-resistant, noninteractive, proxy invisible, key optimal, and nontransitive.We also provided the formal security proof of the proposed scheme in the random oracle ... Webb26 mars 2014 · Our proxy re-encryption scheme is provably CCA-1 secure in the selective model under the LWE assumption. This work proposes a new unidirectional proxy re-encryption scheme based on the hardness of the LWE problem and extends a recent trapdoor definition for a lattice of Micciancio and Peikert.

New identity based proxy re-encryption scheme from lattices

WebbThe growth of galaxies in the local Universe critically depends on the interplay (via outflows and re-condensation) between the hot plasma with the other phases of the interstellar medium (ISM). As a prototype for typical spiral galaxies, the Milky Way offers the unique opportunity to capture the important details of such feedback all the way from sub … WebbProxy re-encryption (PRE) and Proxy re-signature (PRS) were introduced by Blaze, Bleumer and Strauss [Eurocrypt ’98]. Basically, PRE allows a semi-trusted proxy to transform a cipher-text encrypted under one key into an encryption of the same plaintext under another key, without revealing the underlying plaintext. original footwear morristown tnWebbEnter the email address you signed up with and we'll email you a reset link. how to wash white converse sneakers
