Specific embodiments of the invention are as follows:
Mainly adopt asymmetric arithmetic in the present invention, selected RSA Algorithm here in the present embodiment, its authority description document is as follows:
Equipment I d=xxxxxxxxxxxxxxxxxxxx;
Authority A=true;
Authority B=false;
Authority C=false;
The term of validity=2014-12-25 00:00:00;
sign=xxxxxxxxxxxxxxxxxxxxxx；
Wherein, equipment id is, the id of the intelligent home device that can control, and adopts UUID to generate the character string with global unique identifier here, but is not limited to use UUID.
Authority describes list, and authority ABC is the description of various control authority, and wherein true is for allowing operation, and false is not for allowing operation.
The term of validity is the valid expiration date of this authority description document.
Sign adopts UUID to generate the character string with global unique identifier, but is not limited to use UUID.
S1, terminal to server acquisition request are for the authority description document needing the intelligent home device controlled;
For example, in the present embodiment, terminal can be the terminals such as mobile phone, panel computer, personal computer, can also be other possible terminal certainly, not do concrete restriction at this.
After S2, terminal receive the authority description document from server, the intelligent home device controlled with these needs is set up network and is connected;
