Abstract


With the development of the computer technolegy, data safety is more and more important to us. Almost all code system require unpredictable key to encrypt data ,Therefore how to acquire true random number become a urgent problem to people.Nuclear disintegration signal is the natural source of the true random number, the true random sequence acquired form nuclear disintegration is the true random sequence, but it can’t satisfy the requirement of the equality and independence to the random number. So we need to optimize it by software. The article adopts the method to optimize that let the true random sequence with the pseudo random sequence. In order to use the random number acquired furthest, the author designs a control by the VB software which can access the data in a long-distance situation and can be imbedded in a Web.The key technology of the design is introduction and acquisition of nuclear disintegration signal, the optimization to the random sequence and the design of the control which can access the data in a long-distance situation and can be imbedded in a Web. It will be discussed in this paper from several sides.The thesis has four chapters:Chapter 1 introduces the methods designing virtual instrument by LabVIEW and the technology related to the design.Chapter 2 introduces the concept and technology related to the data acquisition and how to use the LabVIEW software to acquiring.Chapter 3 introduces the application of random number in information safety, specially introduces the technology related to the cryptology.Chapter 4 introduces how to design the true random number generator based on the nuclear decay, the theory of system and confirm the equality and independence to the random number.Chapter 5 introduces the design of the identification code generator, the technology of Datasocket and ActiveX and the design of the internet VI based on the ActiveX.
