| Abstract: | Traditional modern cryptology relies in unproven complexity assumptions that certain problems are computationally hard,and the adversary is bounded in computing power.Maurer introduced a new method of constructing cryptosystemthe bounded storage model,where provable everlasting security can be achieved efficiently,This paper investigates the development in advances in cryptology in the bounded storage model.Some problems that are of both theoretical and practical importance,and remain to be solved in the research of HyperEncryption are analyzed. |
