However, through careful analysis, we find that Sood et al.'s protocol is still vulnerable to leak-of-verifier attack, stolen smart card attack and impersonation attack.
This entails the necessity to design new segmentation procedures in order to obtain well structured real verifiers appropriate for applying the classical technique of verifier composition.
Dr. Mousab Azzawi, a consultant pathologist and activist based in London who serves as the group's chairman, said they have a team of 231 verifiers inside Syria consisting of medical doctors, lawyers and other highly trained professionals.
ReprintsApart from launching an offensive against Kosovo's ethnic-Albanian separatists with forces that were supposed, under the October deal, to be kept in barracks, the Yugoslav leader's most provocative move has been to order out William Walker, the American head of an 800-strong team of international "verifiers" in the troubled province.
A common drawback of all existing schemes (including the THRIVE system), which consider the existence of malicious verifiers, is to utilize expensive asymmetric encryptions.
Although scores of OSCE verifiers were deployed throughout Kosovo, hostilities continued.
Providing more efficient constructions (i.e., less communication, storage and computational overheads) while ensuring user privacy in the presence of malicious verifiers is still an open problem.
Overall, the study provides insight on how to harness the learning opportunities arising from EIA follow-up through the appointment of independent verifiers.
Due to severe problems when using low degree algebraic polynomials over the reals as codewords for one of the verifiers to be constructed, we work with certain trigonometric polynomials.
A framework for appraising the role of independent verifiers was established and four South African case studies were examined through a mixture of site visits, project document analysis, and interviews.
