Critical survey of existing publicly verifiable secret sharing schemes
The existing publicly verifiable secret sharing (PVSS) schemes are surveyed in a critical way in this study. The authors show that they are not so reliable and efficient as they claim or appear. They are limited by assumptions and conditions, vulnerable in important target properties and need more cost in practice. In this study, their actual performance and cost are fairly measured and their drawbacks are pointed out.
Establishing transparent workflow distribution across heterogeneous workflow-management systems is very difficult, if not impossible, to achieve. The author expands on this in a case study and suggests various approaches. The process for building a Boeing 747 serves as the case study.
