An all sided, multi tier and multi technical security method has been adopted, which includes identity recognition, data encryption, digital signature, Domino and WWW servers, access control list, directory service, certificate authorization server, IC card and so on. The recognition system based on CA server is a high efficient, convenient and reliable system. The encryption technology and security method are proved to be reliable. The recognition system is of high security and is worthy of being popularized in some places where some special security requirements need meeting. Multi tier technology can improve the security of database. Double keys method is a useful data encryption method.展开更多

To get a big market on the Web, a special security infrastructure would need to be put into place transforming the wild-and-woolly Internet into a network with end-to-end protections. XML (extensible Markup Language) is widely accepted as powerful data representation standard for electronic documents, so a security mechanism for XML documents must be provided in the first place to secure electronic commerce over Internet. In this paper the authors design and implement a secure framework that provides XML signature function, XML Element-wise Encryption function, smart card based crypto API library and Public Key Infrastructure (PKI) security functions to achieve confidentiality, integrity, message authentication, and/or signer authentication services for XML documents and existing non-XML documents that are exchanged by Internet for E-commerce application.展开更多

With the help of modern systematic analysis method, the efficacy of safety incentive mechanisms is discussed in detail. The research shows that more effective avenue to reduce accident is to differently use motivation measures in practice.展开更多

The authors summarize comprehensively the problems of buildings construetion safety in China at present based on grasping the whole safety status of buildings construction, and the synthetic countermeasures including the systems about laws, management, technology and education civilization for buildings construction safety management are brought up based on the viewpoint of safety system theory. Then it is thought that huilding scientific management mechanisms and popularizing effective management methods and measures are the fundamental ways for improving further the level of safety management for buildings construction in China at present.展开更多

Lots of our recent researches have been integrated in this architecture. And the main current researches in the related area have also been absorbed. The main attention of this paper was providing a compact and realizable method to apply ubiquitous computing into our daily lives under sufficient secure guarantee. At last,the personal intelligent assistant system was presented to show that this architecture was a suitable and realizable security mechanism in solving the ubiquitous computing problems.展开更多

Node authentication is not only the basis of network security,but also the premise of key management and secure routing protocol. Although the signature mechanism based on symmetric encryption is high in energy efficiency,it is vulnerable to be attacked and there is a time delay during authentication. Traditional public key encryption mechanism with improvement in security brings in complex algorithm and costs much time,which is not suitable for WSN. In this paper,a signature authentication mechanism,an optimized variant Bellare Namprempre Neven( OvBNN) is presented to quickly complete the authentication by mutual cooperation between nodes so as to make the nodes use the intermediate calculation results of their neighbor nodes directly.Simulation results show that the proposed mechanism is superior to traditional authentication mechanisms both in energy consumption and authentication time.展开更多

With the rapid development of the network platform, it is connected to the number and size of the trusted computing environment for all kinds of applications that are rapidly expanding, ever-changing network health, network time being emergencies, assault, failure, threat of disaster, its safety, survivability and availability of face serious challenges. Although TNC Working Group made safe and reliable framework from the network access layer, it is not at the level of user access, system access levels and further given the level of situational awareness and effective solutions.展开更多
