In 1986, an American expert on information management science called Richard O. Mason, after a long time study, puts forward 4 major ethical topics for discussion in the information age: information privacy, information accuracy, information property right and information resources access right.
This article discusses the new problems in Mason PAPA theory of information ethics in the network era: the conflict between information privacy and information share, the information accuracy and the moral hazard problems, information property right and information transactions, information resources access right and information justice.
We need to launch logic basic point from the right of network privacy protection theory,discuss value significance of network privacy,select the system ensemble protection pattern which the choice is suitable by establishes the benefit balance mechanism between the right of network privacy and the information liberalization.
So, at the year of 1997, the IEEE established the 802.11 standard for WLAN, and such standard uses the mechanism of WEP(Wired Equivalent privacy), which based on the algorithm of RC4, to improve its security.
The naturalness, privacy and ethicalness of the sex behavior, and the principle of intervention to the sex behavior by the public power, decide both the difficulty and its limitation of the intervention and control of the sex by the public power.
In order to protect the information privacy of users, some mechanisms such as RADIUS and ESSID Authentication, Mac Address filtering and WEP, etc are used.
Based on the authentication mechanism of the public key certificate, S/MIME and TLS provide privacy, authentication, no denying and integrality protection, are better solutions.
But being a message channel with privacy and publicity,the influence of celebrity on internet blog,and the intervention from commerce and politics power,these factors to some extent weaken the positive effects of blog and influence its future prospective.
The analysis of the proposed scheme shows that it satisfies non-transferability, unforgeability and privacy of the signer's identity and has to low computational cost.
For ensuring the safety of QSDC with single photons and quantum information sharing of single qubit in a noisy channel, a quantum privacy amplification protocol has been proposed.
In this paper we put forward a preliminery plan for a FH/DS spread spectrum communication which has the ability of suddenly-happen communication compatible with voice. It can be used in mobile communication network. There is only 0.2 second for completing a suddenly-happen communication. The operating frequency is 225-400 MHz and is easily communicated with existing transceiver. The system has the capability to reject jamming, low probability of intercept and provides message privacy because advanced ...
Nowadays the spread spectrum commuuication system is paid more attention to the advantages of multiple access, antijamming and message privacy. In this paper, we discuss the design of frequency hopping multiple-access code for the establishment of spread spectrum communication network. The relation between code-length, number of channels and number of networks is derived. The design of FH multiple-access code adapting for multi-network is put forward.
This paper presents some classifications of the network servers in Local Area Networks. Some properties of the servers network's control, sharing and communication, file allocation table, and data's privacy are discussed in detail. They are very important to the designer as well as to the users.
