Web5 de ago. de 2024 · Attribute-based encryption (ABE) cryptography is widely known for its potential to solve the scalability issue of recent public key infrastructure (PKI). It provides a fine-grained access control system with high flexibility and efficiency by labeling the secret key and ciphertext with distinctive attributes. Due to its fine-grained features, the ABE … WebAbstract. It is a long standing open problem to ﬁnd search to decision reductions for structured versions of the decoding problem of linear codes. Such results in the lattice-based setting have been carried out using number ﬁelds: Polynomial–LWE, Ring–LWE, Module–LWE and so on. We propose a function ﬁeld version of the LWE problem. WebThe original LWE problem is de ned over lattices and is not very e cient due to the use of large matrices. A more computationally e cient variant of the problem, known as the ring-LWE problem was introduced by Lyubashevsky, Peikert and Regev in [21]. The ring-LWE problem is de ned over a polynomial ring R q = Z flow classic faucet
