Fig. 3 is the message transmission schematic diagram of the method for shared information between devices according to an embodiment of the invention. In this embodiment, equipment Qi requests the information of query term by server P to other equipment Qs.Here, Qs refers to other one A or multiple equipment.It is appreciated that in other embodiments, Qi can in a similar way with it is any in addition to Qi equipment Preserve the other collaborative share information of information.Some steps of the embodiment are described below, but it is understood that, these steps Some processes in rapid are only exemplary, and are not limited the invention.

Step 301

Inquiry request is sent from the first equipment Qi to server P, which includes the first of the major key M of item to be checked Hashed value HM and corresponding first hashed password SQi, wherein HM=HASH (M, SQi).

In some instances, HASH (A, B) is indicated for text A, carries out mould and operation with B, then carry out uni-directional hash fortune It calculates.Such as MD5, the algorithm of the uni-directional hash operation such as SHA-1, SHA-256 can be used.

In some instances, optionally, inquiry business type Type also is sent to server P from the first equipment Qi.This can To allow server P that inquiry request is targetedly forwarded to other equipment of the item with the type of service.

In some instances, first hashed password SQi is the hashed value based on search sequence QiID, corresponding to hash Password is the public key PKQi of the first equipment Qi, wherein SQi=HASH (QiID, PKQi).In other examples, this One hashed password SQi is the hashed value based on search sequence QiID and Query Dates Date, at this moment SQi=HASH (QiID+ Date,PKQi).The default starting QiID of first equipment Qi can be set to 0, and subsequent QiID can be sent to Qi from by P.

After sending inquiry request to server P from the first equipment Qi, the Type, HM, SQi of Qi storage this time inquiry, M。

Step 302

It include the information of the first hashed value HM and the first hashed password SQi from server P to the second equipment Qs forwarding.

In some instances, to improve safety, at server P, inquiry of the verifying from the first equipment Qi is asked It asks, wherein using the search sequence QiID " and public key of the first equipment Qi for being stored in advance in server P, PKQi ", Hashed value SQi " is calculated using hash function using public key as hashed password as initial data in search sequence number, In, SQi "=HASH (QiID ", PKQi ").When the hashed value SQi " is consistent with the first hashed password SQi, the verifying is judged Success.

In some instances, after being proved to be successful, Type, HM, SQi are broadcasted from server P to Qs, and can also be thus Start timing.

In some instances, in the second equipment Qs, using SQi to multiple major key N of the business of parameter Type one by one It carries out hash operations and obtains hash value list.

Then, the shared key TK encrypted and first hashed value are sent from the second equipment Qs to the server P In some instances, shared key TKs, which can be, to be generated by Qs by the hashed value (that is, HM) matched, the first hashed password SQi Random number, and TK can obtain TK=C (TKs, M) by following formula.Here, C (A, B) is indicated for text A, the use of B is secret The result of key progress symmetric cryptography.C " (A, B) is indicated for text A, the use of B is that code key is symmetrically decrypted.It can be used The symmetric cryptographic algorithms such as 3DES, AES, SM1.In other examples, symmetric cryptography is carried out using the hash value of M to TKs, at this time TK=C (TKs, HASH (M, 0)).Second equipment Qs records TKs, TK, M.

Step 304

The shared key TK of the encryption is forwarded from the server P to the first equipment Qi, is hashed with described first It is worth matched hashed value, the first hashed password SQi.P records TK and Qs mapping relations.

In some instances, P is after the feedback result for receiving all Qs, or after timing reaches default maximum duration, shape At the quantity N of final query result R, Qs, shared code key list TKlist.It is then possible to from P to Qi send Type, SQi, R, N, TKlist, QiID ", QiID " is the search sequence number for initiating inquiry next time here.

Step 305

After first equipment Qi obtains Type, SQi, R, N, M can be obtained by Type, SQi in inquiry record.First Equipment Qi can also judge whether shared range is enough by the size of N numerical value, and updating QiID is QiID '.

In the first equipment Qi, the shared key TK of the encryption is decrypted using the major key M of the item to be checked, and using should Shared key TKs encrypts the attribute-name Si to be checked, and the attribute-name CSi and TK of encryption are sent to the server.Here, TKs=C (TKs, M).In one example, acquisition is decrypted using HM0=HASH (M, 0) for each TK in TKlist It is point-to-point to share symmetrical code key TKs, i.e. TKs=C " (TK, HM0).The mapping relations of Qi record TK and M, TKs.

Step 306

According to the mapping relations of TK and Qs, sending from server P to one or more of hit equipment Qs should add Close attribute-name CSi and TK.P supplements TK and Qi relationship.

Step 307

In each of one or more of hit equipment Qs, the major key or HM0=of the hit item are utilized The attribute-name that HASH (M, 0) decrypts the encryption obtains the attribute-name, and encrypts corresponding category using the major key of the hit item Property value Si_V, and to server P send encryption attribute value CSi_V, TK.

Step 308

Attribute value CSi_V, TK of the encryption are sent from server P to the first equipment Qi.Qi obtains CSi_V, It is mapped, is decrypted Si_V=(CSi_V, TKs) according to TK, M, Tks.
