On the hardness of the NTRU problem - IACR
Webcryptosystem of McEliece [22]. The security of GGH is related to the hardness of ap-proximating the closest vector problem (CVP) in a lattice. The GGH article [9] focused on encryption, and five encryption challenges were issued on the Internet [10]. Two years later, Nguyen [29] found a flaw in the original GGH encryption scheme, which al- WebThe first encryption scheme utilizing properties of polynomial rings was NTRU (ANTS ’98), but in the recent decade, most research has focused on constructing schemes based on the hardness of the somewhat related Ring/Module-LWE problem. Indeed, 14 out of the 17 encryption schemes based on the hardness of lattice problems in… View Paper the pit roanoke field
NTRUReEncrypt: An Efficient Proxy Re-Encryption Scheme Based on NTRU
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. [34] introduced a struc- Web1 de jan. de 2002 · As we explain, some of our attacks on Revised NSS may be extended to NTRUSign, but a much longer transcript is necessary. We also indicate how the security of NTRUSign is based on the hardness of several problems, not solely on the hardness of the usual NTRU lattice problem.
