為 了提高用戶身份認(rèn)證和授權(quán)管理的靈活性,從We b 應(yīng)用系統(tǒng)的安全性角度出發(fā),討論了 一 種在. N E T F r a me w o r k下保證應(yīng)用程序安全性的身份驗(yàn)證和授權(quán)模型,并給出了模型的具體實(shí)現(xiàn)方法。 該模型利用 F o r ms身份驗(yàn)證方法對(duì)用戶的身份進(jìn)行鑒別。在授權(quán)處理上,模型結(jié)合統(tǒng)一資源定位( u .

Generate Possion Dis. step1:Generate a random number between [0,1] step2:Let u=F(x)=1-[(1/e)x] step3:Slove x=1/F(u) step4:Repeat Step1~Step3 by using different u,you can get x1,x2,x3,...,xn step5:If the first packet was generated at time [0], than the second packet will be generated at time [0+x1],The third packet will be generated at time [0+x1+x2], and so on …. Random-number generation 1.static method random from class Math -Returns doubles in the range 0.0 <= x < 1.0 2.class Random from package java.util -Can produce pseudorandom boolean, byte, float, double, int, long and Gaussian values -Is seeded with the current time of day to generate different sequences of numbers each time the program executes
