The formula of encrypting has many kinds, several bit shift positions, for example, all adjacent bit switches of information are launched again, so, the 1st and the 2nd bit may become 01, the 3 and the 4th bit by original 10 and may become 10 by 01, upset original information in an orderly manner, other people have been received, go out deciphering and do not come out, have only this corresponding BB machine, its decrypting device has been carried out this conversion of returning, receive the back and just become 01 of the 1st and the 2nd bit again 10,10 of the 3rd and the 4th bit is become again 01, or the like, so just real prime information is deciphered out, and show.
Cipher mode (formula) can have many kinds, for example in the information, its the 1st bit and the 3rd bit are exchanged by one group of 3 bit, or exchange or the like by one group of preceding two bit of 4 bits and latter two bit, new secret formula is reached in the capital, the various permutation and combination of each bit change, and can constitute the possible secret formula of enormous amount.
For concrete secret formula, the machine master of BB machine also is not concerned about, every kind of secret formula all is provided with a code name, for example 000111,012345 or the like, each represents different secret formulas, the machine master is as long as program step is in accordance with regulations pressed its BB switch dish, with for example 000111 input of secret formula code name, just make its BB machine adopt 000111 deciphering formula, its BB machine will be decrypted by formula.At this moment, the machine master is procedure operation in accordance with regulations again, makes the page transmission device when giving his BB machine emission information, adopts 000111 secret formula (encryption) emission, and then emission is just all consistent with the secret formula that receives, and has just realized maintaining secrecy of machine master paging information.
For example 000 mode or 111111 modes are that it also is a kind of of secret formula (mode), is such setting in the time of may dispatching from the factory as the mode that need not encrypt again, when needing other secret formula, by the machine master voluntarily follow procedure change.
Because secret formula can be decided in its sole discretion by the machine master, and secret formula enormous amount, so when needing, the machine master can change the secret formula of own BB machine at any time.
The secret mode of native system can be different because of every BB machine.
So just reached the purpose that paging information is maintained secrecy.
