The C programming language is expressive and flexible, but not safe; as its expressive power and flexibility are obtained through unsafe language features, and improper use of these features can lead to program bugs whose causes are hard to identify. Since C is widely used, and it is impractical to rewrite all existing C programs in safe languages, so ways must be found to make C programs safe. This paper deals with the unsafe features of C and presents a survey on existing solutions to m… 相似文献

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.

Secret sharing and digital signature is an important research area in information security and has wide applications in such fields as safeguarding and legal use of confidential information, secure multiparty computation and electronic commerce. But up to now, study of signature based on general vector space secret sharing is very weak. Aiming at this drawback, the authors did some research on vector space secret sharing against cheaters, and proposed an efficient but secure vector space se… 相似文献

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
