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 design and realization of the network system includes the structure of the network system, the cabling system, the two layer switch system, the Windows 2000 Domain and the basic safety and security system, and its integrated.
According to the requirement of City Emergency Response System(CERS),some important problems need to be emphasized,such as technology of information integrated sharing,construction of Public Security "3 in 1" Emergency Response System and Geography Information System(GIS),are analyzed.
According to the method of the system engineering, the thesis analyzed the functions, the demands and weaknesses which influence the national personnel information management system. The thesis makes the emphasis on the safe and secret system, the security goal and security tactics of the network.
This text is from the basic characteristic of network information safety, influences a network information safety keep secret of main manifestation and should adopt of administration, technique and law means, analyze calculator network information a safety to keep secret to work in brief of guard against a counter plan.
In this paper, we use a direct method to solve the optimal portfolio and consumption choice problem in the security market for a specific case, in which the utility function is of a given homogenous form, i.e.
This paper analyzes the aritrage-free security markets and the general equilibrium existence problem for a stochastic economy with incomplete financial markets.
Linear provable security for a class of unbalanced feistel network
Application of this structure to block cipher designs brings out the provable security against linear attack with the upper bounds of probabilities.
Trust management was discussed according to the security requirements in distributed environment.
