Web1 de set. de 2024 · 1 Introduction. Recently, lattices have been found to be of immense importance in cryptography. The traditional number-theoretic hardness assumptions (like factoring and discrete log problems) are not safe against quantum algorithms [], but the hard lattice problems are believed to have negative quantum threats.Further, the worst-case … Web12 de abr. de 2024 · The DES (data encryption standard) is one of the original symmetric encryption algorithms, developed by IBM in 1977. Originally, it was developed for and used by U.S. government agencies to protect sensitive, unclassified data. This encryption method was included in Transport Layer Security (TLS) versions 1.0 and 1.1.
WebI am a postdoctoral researcher at COSIC, KU Leuven, Belgium.

Web29 de out. de 2014 · 1 Answer. Sorted by: 7. NTRU, as it was originally introduced, is based on what people now call the "NTRU assumption", which really just assumes that it is difficult to break NTRU. Annoyingly circular, but that's how it is. Similar to how breaking RSA is not provably as hard as factoring (technically it is based on the "RSA assumption"), but ...
