All nodes.
That is, in embodiments of the present invention, when receiving logistics information, can judgement decrypt described present node
Logistics information；When determining that itself can decrypt the logistics information, the nodal information of next node is determined；According to the logistics
The nodal information of information, the nodal information of the present node and the next node, generation area block；By the block body
It is written in block chain, and is broadcasted to all nodes where the block chain as new logistics information.Compared with the prior art,
In embodiments of the present invention, each node, all can be according to logistics information, itself section when determining that itself can decrypt logistics information
The nodal information of point information and next node, generates corresponding block body, without relying on corresponding host node, so as to
Guarantee the safety of logistics information.
It should be noted that the logistics information generally can be a block body, wherein may include corresponding Item Information,
The nodal information etc. of a upper node, does not repeat this.
Specifically, present node determines that itself can decrypt the logistics information, specifically can include:
Present node determines that own private key can decrypt the logistics information.
It, can be by itself private key it should be noted that present node is when receiving the block body including logistics information
The block body is decrypted, when the block body can be decrypted, illustrates that present node can be a biography of the logistics information
Defeated node does not repeat this.
Specifically, according to the node of the logistics information, the nodal information of the present node and the next node
Information, generation area block, specifically can include:
It is raw according to the flag information of the logistics information, the flag information of the present node and the next node
At original area block；

Determine that the logistics information is not tampered with.
It should be noted that the processing of Hash described in the embodiment of the present invention may include the Hash for calculating the logistics information
(hash) value, and compare the cryptographic Hash in itself calculated cryptographic Hash and the block body, however, it is determined that the two is consistent, Ji Kebiao
Show that the logistics information in transmission process of the upper node-node transmission to present node, is not tampered with, belongs to believable logistics
Information does not repeat this.
Further, it may also include random number in the block body, this do not repeated.
As shown in figure 4, it is the information exchange schematic diagram between each node provided in the embodiment of the present invention one.Specifically,
As shown in Figure 4, user (i.e. active user) corresponding to the present node (node A as shown in Figure 4) is receiving logistics
It, can be on the nodal information according to the logistics information, the nodal information of the present node and the next node when information
Pass to present node；Present node can according to the logistics information, institute's data present node nodal information and it is described under
The nodal information of one node generates corresponding block body；Present node calls TSA server acquisition time to stab information, and to described
Block body is signed, to guarantee the non repudiation of logistics information；Present node calls KM server, obtains next node
Public key, and according to the public key of the next node, the block body is encrypted；Can calculation block body cryptographic Hash, obtain
Hash file, and can be according to encrypted area block and Hash file, generation area block；The block body is broadcasted to the block
Each node in chain, node B as shown in Figure 4, node C and node D, does not repeat this.
In the following, citing is situated between in detail to the logistics transmission method described in the embodiment of the present invention based on block chain
It continues:
