On the Security of HMAC and NMAC Based on HAVAL, MD4, MD5, SHA-0 and SHA-1 (Extended Abstract)ons from a random function or from HMAC with a random function. We also show how to use our differential distinguisher to devise a forgery attack on HMAC. Our distinguishing and forgery attacks can also be mounted on NMAC based on HAVAL, MD4, MD5, SHA-0 and SHA-1.

Relations Among Security Notions for Undeniable Signature Schemesn message attack is equivalent to invisibility against full attack. We also present an undeniable signature scheme whose unforgeability is based on the factoring assumption and whose invisibility is based on the composite decision Diffie-Hellman assumption.

Ideal Secret Sharing Schemes Whose Minimal Qualified Subsets Have at Most Three Participants structures with rank three that are related to matroids with rank greater than three are ideal. After the results in this paper, the only open problem in the characterization of the ideal access structures with rank three is to characterize the matroids with rank three that can be represented by an ideal secret sharing scheme.

Cheating Immune (2,,)-Threshold Visual Secret Sharings or images as done in . We have provided a formal definition of cheating which requires that a group of cheaters be able to deterministically force a honest participant to reconstruct a wrong secret. The (2,.)-threshold schemes that we provide do not allow such cheating, regardless of the number of cheaters.
