Abstract
The invention provides an encryption publishing method for privacy information in a smart power grid. The method comprises the following steps: registering to a social network through a user, and verifying user information; performing key management on the user information; establishing a two-level privacy information word library; and operating a friend list and publishing information. Through adoption of the method provided by the invention, the user is automatically prompted to protect personal privacy information; the personal safety of the user can be ensured practically; and visitors of the social network are increased. The privacy information of the user is encrypted, and a public key is relevant to user identity information and easy to acquire, so that trouble in generating a key, managing the key and authenticating the public key and user consistency by a trusted third party is omitted compared with other public-key cryptosystems. Meanwhile, overhead caused by a public-key cryptosystem encryption algorithm is saved.

From the viewpoint of relation and information two, the intimacy protection system released news in a kind of intelligent grid is proposed.This system mainly comprises following step, as shown in Figure 3:
Concrete steps:
(1) information of registered users.According to application and the level of security of social networks, user's registration information can be divided into real name and non-real name two class, determines the need of note or mailbox checking according to demand for security.
(2) key management.Because the present invention uses the public-key encryptosystem encryption privacy information of identity-based information, relate to key management link.Consider that social networks releases news and be divided into following several situation: distribute one to one, friend group is issued and everyone is published, discuss one by one below:
I) distribute one to one: send the public-key cryptography of user with reception user, i.e. user ID, encryption privacy information is issued, and receives user and is decrypted information with individual private key.
II) friend group is issued: be each mass-sending cloth a pair public-key cryptography and private cipher key, public-key cryptography is group number, private cipher key is generated by background server and secret is sent to each crowd of users, in this group, each user has public-key cryptography and the private cipher key of group simultaneously, use public key encryption privacy information, use private cipher key decryption information.New user and Xin enter crowd user and obtain cipher key processes and the flow process that releases news first respectively as shown in Figure 4 and Figure 5.
III) everyone is published: take random key to encrypt privacy information, any user can check, but cannot decipher for privacy information, can only obtain ciphertext form.
(3) two-stage privacy information dictionary is set up.Set up privacy information dictionary object not revealed unintentionally at utmost protect individual subscriber privacy information.Arrange the mode of two-stage privacy dictionary, one-level privacy dictionary is based on server is recommended, and secondary privacy dictionary comes perfect by user's interpolation, deletion, amendment.Server is recommended can based on some common privacy informations, such as common name, " Wang Yong ", " Zhang Hong "; " be born in "; " work unit "; " home address "; " so-and-so producer "; The keyword of privacy information may be there is in " so-and-so brand power equipment " etc.The keyword that server just recommends part common, more needs user perfect voluntarily.Except text message, the multimedia messages such as picture, audio frequency, video of some sensitivities also can be added into secondary privacy dictionary by user.
(4) buddy list is safeguarded.User adds familiar good friend user voluntarily, or deletes the user lost faith in, and also can set up group, invites good friend to enter group, release group information.
(5) Information issued.Once establish privacy information dictionary, can, by the privacy information that relates in information according to different reception objects, adopt the method in above-mentioned steps (2) to be encrypted, other non-privacy informations adopt mode expressly to issue.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; although with reference to above-described embodiment to invention has been detailed description; those of ordinary skill in the field still can modify to the specific embodiment of the present invention or equivalent replacement; and these do not depart from any amendment of spirit and scope of the invention or equivalent replacement, it is all being applied within the claims of the present invention awaited the reply.
