设f(x)=1+x+x2+x5+x27，试分别写出实现下列移位寄存器的程序： 以f(x)为联接多项式的DSR； 以f(x)为联接多项式的LFSR。 可供选择的联接多项式： f1(x)=1+x+x4+x6+x30； f2(x)=1+ x3+ x31； f3(x)=1+ x6+ x31； f4(x)=1+ x7+ x31； f5(x)=1+ x13+ x31； -Let f (x) = 1 x x2 x5 x27, respectively try to write the following Shift Register : f (x) connected to the DSR polynomial; f (x) for connectivity polynomial LFSR. Connection options polynomial : f (x) = 1 x x4 x6 x30; F2 (x) = 1 x3 x31; f3 (x) = 1 x6 x31; f4 (x) = 1 x11 x31; f5 (x) = 1 x13 x31;

RSA资料全集是我在学习RSA时收集的资料，它对我学习这种算法有着极大的帮助，不知对大家有帮助没有，希望对大家学习密码学有所帮助。-All of the information of RSA was collected when i was studying RSA.It gives me a great deal of help though i don t know how about you.I wish it also give you some help about the cryptology.

这个是基于混沌的DES算法-this is based on the DES algorithm Chaos
