Distributed certification via threshold cryptography is much more secure than other ways to protect certification authority
(CA)'s private key, and can tolerate some intrusions. As the original system such as ITTC, etc., is unsafe, inefficient and
impracitcal in actual network environment, this paper brings up a new distributed certification scheme, which although it
generates key shares concentratively, it updates key shares distributedly, and so, avoids single-point failure like ITTC.
It not only enhances robustness with Feldman verification and SSL protocol, but can also change the threshold (t, k) flexibly and robustly, and so, is much more practical. In this work, the authors implement the prototype system of the new
scheme and test and analyze its performance.

INTRODUCTION The development of network technology led to the appearance of many high-speed networks with bandwidth larger than 1 Gbps, or even 10 Gbps. Through high-speed networks, applications like sci- entific collaboration, telemedicine, and real-time environment monitoring can transfer high-bandwidth real time data, images, and video captured from re- mote sensors such as satellite, radars, and echocar- diography. What is more, data intensive grid applica- tion (Foster et al., 2001)… 相似文献
