Ideal Secret Sharing Schemes Whose Minimal Qualified Subsets Have at Most Three Participantsthe results by Brickell and Davenport, every one of those access structures is related in a certain way to a unique matroid. We study this open problem for access structures with rank three, that is, structures whose minimal qualified subsets have at most three participants. We prove that all access

Rational Secret Sharing, Revisitedlution is . for .=2 but show a solution for the case .≥3. Contrary to their claim, we show a protocol for rational secret sharing among .=2 players; our protocol extends to the case .≥3, where it is simpler than the Halpern-Teague solution and also offers a number of other advantages. We also show h

On the Security of HMAC and NMAC Based on HAVAL, MD4, MD5, SHA-0 and SHA-1 (Extended Abstract)t has been standardized by ANSI, IETF, ISO and NIST. HMAC is proved to be secure as long as the compression function of the underlying hash function is a pseudorandom function. In this paper we devise two new distinguishers of the structure of HMAC, called . and ., and use them to discuss the securi

On Statistical Testing of Random Numbers Generators analysis of this test we propose simple and effective methods for its improvement. These methods are related to the . – spacing technique common in goodness-of-fit problems and the . – leave out method used for a noise reduction in the final Maurer test statistic. We also show that the spacing dist
