WebThis work provides two answers to the long-standing open problem of providing reduction-based evidence of the hardness of the NTRU problem by reducing the worst-case approximate Shortest Vector Problem over ideal lattices to an average-case search variant of the EMM problem. 12 PDF Robustness of the Learning with Errors Assumption WebThe 25 year-old NTRU problem is an important computational assumption in public-key cryptography. However, from a reduction perspective, its relative hardness compared to other problems on Euclidean lattices is not well-understood. Its decision version reduces to the search Ring-LWE problem, but this only provides a hardness upper bound. WebLattice Attacks on NTRU Revisited. NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension 2N. Many researchers conjecture that the private key vector is indeed the shortest vector in the lattice in most cases. list of christmas movies 2016

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 … Webfunction was proven collision-resistant under the assumed hardness of the modi-fied average-case problem, called Ideal-SIS. The latter was itself proven at least as hard as the restrictions of standard worst-case lattice problems to a specific class of lattices (called ideal lattices). In 2009, Stehlé et al.
