Zero-knowledge proofs of decision power: New protocols and optimal round-complexity,finition of the model, and then extend the class of languages in it; (so far only the language of quadratic residuosity modulo a Blum integer was known to be applicable to this model). More precisely, we present a protocol for all known random self-reducible languages (i.e., graph isomorphism, quadr

A language for specifying sequences of authorization transformations and its applications, policy base which consisted of a finite set of facts and a finite set of access constraints. In this paper, we modify the language to consider a sequence of authorization policy transformations. The syntax and semantics of the modified authorization policy language is presented. The central issue a

Traceable visual cryptography,efined by Naor and Shamir [5] but is also traceable. A . out of . visual cryptography scheme is a special instance of a . out of . threshold secret sharing scheme [6]. Thus, no information about the original secret can be revealed if less than . share-holders combine their shares. In those systems i

Remarks on the multiple assignment secret sharing scheme,t it is proved that the proposed multiple assignment secret sharing scheme is not perfect. In fact, the non-perfectness of the scheme is due to the non-perfectness of a certain type of Shamir secret sharing scheme defined in the paper. Next, it is shown that both the extended multiple assignment sec

Design of a security platform for CORBA based application,ystem. SOAP supports CORBA security specification announced by OMG. SOAP is composed of four functional blocks which co-work with ORB to provide security services: Authentication Block, Security Association Block, Access Control Block, and Security Information Management Block. It is designed to sup
