Research On The Extendable Method Of Random Sequence, And Analysis And Application In Sequence Cryptography With It

Several thousand year agos, the cryptogram system has already used for military and diplomacy communications. At today of information ages,the personal correspondence, multimedia correspondence, E-mail, electronics of the public correspondence facilities and the calculator network and retail the business net develop rapidly and information of of safety and protection seems to be more important. the application in encrypt nowadays is more extensive, and it's importance has already no longer limitted at the politics, military and the diplomacy realms, its antenna also goes deep into the business realm and social realms. In this paper i put forward the thought that a new method can be used to get encrypt sequence by the studying in Encrypt System. Make use of the thought that the kronecker product can extend the matrix to the sequence.And I analyzed the characteristic of secquence the enlarged by Kronecker product .Finally I take the thought into realization through VC6.0. This paper mainly complete such tasks as follows: 1 Studying current cryptogram system. The pivot is the linear and nonlinear feedback replacement register which are usually applied in the sequence cryptogram system. 2 Put forward the thought that a new method can be used to get encrypt sequence by the studying in Encrypt System. 3 Studying the ways to process the security and random city examination for the sequence cryptogram. 4 Analyze the characteristic of secquence the enlarged by Kronecker product. 5 Carrying through some statistical analyse for the inborn secret key sequences. 7 Carrying out the arithmetic through VC++6.0.
