We show that in the context of nonuniform complexity, nondeterministic logarithmic space bounded computation can be made unambiguous. An analogous result holds for the class of pr...
-- The substitution box (S-Box) is one of the most important components in modern ciphers. This paper reports a new class of S-Boxes defined by the logarithmic functions in GF(16)....
Key authentication is very important in private communication and data integrity. Recently, Peinado, Zhang and Kim showed that the LHL scheme is not secure, respectively. From pub...
This paper derives the multi-layer heat conduction Green’s function, by integrating the eigen-expansion technique and the classic transmission line theories, and presents a loga...
We construct simple algorithms for high-dimensional numerical integration of function classes with moderate smoothness. These classes consist of square-integrable functions over t...
