First embodiment
Referring to fig. 3, fig. 3 is a flowchart of an information publishing method according to a first embodiment of the present invention, where the method is applied to a first device. The flow shown in fig. 3 will be described in detail below, and the method includes:
step S101: first equipment in the Internet of things generates an information release request and information release content corresponding to the information release request. Further, the first device may perform a hash operation on the first device public key and the first device ID (each device in the internet of things has a unique ID (e.g., a globally unique serial number, UUID)) that are pre-stored locally, so as to obtain a digest value. After the digest value is obtained, digital signature operation is carried out on the digest value based on the first device private key which is stored locally in advance, and a signature result is obtained. The first device may further combine the digest value and the signature result according to a first preset format to generate an information release request, and combine the first device ID and the first device public key according to a second preset format to generate information release content. The purpose that the first preset format and the second preset format can be adjusted and set to be uniform according to actual conditions is to ensure that data can be conveniently viewed and processed.
Step S102: the first device searches a block chain, when a pre-stored information release request which is the same as the information release request does not exist in the block chain, the first device releases the information release request to the block chain network, and waits for the block chain network to write the information release request into the block chain.
And the first equipment searches the block chain and judges whether a pre-stored information release request with the same abstract value as the information release request exists in the pre-stored information release request or not. If yes, canceling information writing; if not, the first device continues to judge whether a pre-stored information release request with the same signature result as the information release request exists in the pre-stored information release request. If yes, canceling information writing; and if the information distribution request does not exist, the first equipment distributes the information distribution request to the block chain network and waits for the block chain network to write the information distribution request into the block chain.
Step S103: and the first equipment searches the block chain, and when the pre-stored information release content which is the same as the information release content does not exist in the block chain, the first equipment searches whether the information release request matched with the information release content exists in the block chain.
The first device searches the block chain, and judges whether pre-stored information release content identical to the first device ID or the first device public key included in the information release content exists in the pre-stored information release content. If yes, canceling the writing; and if not, the first equipment performs Hash operation on the basis of the information release content to obtain an abstract value of the information release content, and judges whether a target information release request with the same abstract value as the information release content exists in the prestored information release requests stored in the block chain. If not, canceling the writing; if so, judging whether the first device private key included in the signature result of the target information publishing request is matched with the first device public key included in the information publishing content.
Step S104: if the information release content exists, the first device releases the information release content to the block chain network, and waits for the block chain network to write the information release content into the block chain.
When the first device private key included in the signature result of the target information publishing request is judged to be matched with the first device public key included in the information publishing content, the first device publishes the information publishing content to the block chain network, and the block chain network is waited to write the information publishing content into the block chain. The information release content is the first information.
Once written into the block chain, the information cannot be tampered and cannot be revoked. Therefore, the first device for issuing the data record can be identified as the issuer of the information issuing content according to the writing record of the information. The publisher of the information release content has the time advantage of knowing the specific content of the information in advance, and by utilizing the time advantage and the non-tamper property of the block chain, the information is safely released and the safety binding of various logic relationships is realized in a mode of firstly releasing the hash value of the information on the block chain and then releasing the specific content of the information after confirmation.
It should be noted that the information distribution request and the information distribution content writing process of the second device are similar to the above process, and are not described herein again.
In addition, referring to fig. 4, as an embodiment, the method may further include:
step S110: and the first equipment in the Internet of things receives the second equipment ID sent by the second equipment in the Internet of things.
Each device in the internet of things has a unique ID (e.g., a globally unique serial number, UUID), wherein the first device ID and the second device ID may both be stored in a device local storage area.
Step S120: based on the second device ID, the first device searches the block chain to obtain second information comprising the second device ID and a second device public key.
As an implementation manner, the first device may perform lookup in a pre-stored blockchain based on the received second device ID, and obtain second information matched with the second device from the lookup, where the second information includes the second device ID and a second device public key, that is, content issued by the second device in the blockchain. Of course, the second information may be issued in advance by the second device and stored in the blockchain.
Step S130: the first device obtains authentication information from the second device.
The identity verification information is calculated by the second device based on the first information and the third information. Wherein the first information includes the first device ID and a first device public key, and the third information includes the second device ID and a second device private key. The first information may be obtained by the second device by looking up in the blockchain based on a first device ID obtained in advance, and the second information may be generated by the second device based on a parameter saved in the second device in advance and saved in the second device.
Further, the second device may calculate a value as the authentication information through a cryptographic algorithm based on the first information and the third information.
It is worth pointing out that there are also parameters pre-stored locally in the first device. The parameters pre-stored locally may be configured by a programming method when the manufacturer manufactures the device. Wherein the parameters may include: device ID, cryptographic algorithm, security parameters, and configuration information. Both the first device and the second device may calculate a public key and a private key belonging to the devices based on the security parameters and the cryptographic algorithm. Since the calculation is performed by the same cryptographic algorithm, the private key and the public key of the same device match each other.
Of course, before the first device obtains the authentication information from the second device, the first device may send the first device ID to the second device in advance, so that the second device may search for the first information corresponding to the first device in the blockchain based on the first device ID.
Step S140: and the first equipment judges whether the identity authentication information meets a preset condition or not.
Wherein the preset condition may be: and when the first device authenticates the identity authentication information based on the first device ID, the first device private key, the second device ID and the second device public key, the authentication is passed.
Step S150: if so, the first device determines that the authentication between the first device and the second device is successful.
Of course, if the result is negative, the first device determines that the authentication fails, and may actively close the secure communication with the second device.
Further, after the first device obtains second information including the second device ID and the second device public key based on the second device ID sent by the second device, the first device may also generate authentication information based on the first device ID stored locally and the first device private key (i.e., fourth information), and send the authentication information to the second device, so that the second device may also perform authentication.
As an implementation manner, on the premise that the first device successfully verifies the second device, if the second device also successfully verifies the first device, that is, if the two-way verification is successfully achieved through the two devices, it may be determined that the reliable binding relationship is established between the first device and the second device. Further, after the reliable binding relationship between the first device and the second device is determined, the first device and the second device can perform session key agreement through cryptographic operation on the basis of binding, and encrypt data interaction between the second device and the second device by using the session key.
As another embodiment, on the premise that the first device successfully verifies the second device, if the second device fails to verify the first device, that is, the mutual authentication fails, the first device determines that the binding between the first device and the second device fails.
The information issuing method provided by the first embodiment of the invention has the beneficial effects that: the method comprises the steps that a first device in the Internet of things generates an information release request and information release contents corresponding to the information release request in advance, whether a pre-stored information release request identical to the information release request exists or not is searched in a block chain, if the pre-stored information release request does not exist, the information release request is released to a block chain network to be stored, whether pre-stored information release contents identical to the information release contents exist or not is searched in the block chain, if the pre-stored information release contents do not exist, whether the information release request matched with the information release contents exists or not is searched in the block chain, if the pre-stored information release contents exist, the information release contents are released to the block chain network, the block chain network is waited to write the information release contents into the block chain, and information release is completed. The information issuing method avoids tampering of the information issuing content, avoids participation of a third-party organization in the whole information issuing process, relieves the problem of dependence of traditional information security issuing on the third-party organization, and reduces the problems of high cost and low efficiency caused by dependence of the Internet of things on a centralized server.

the first device verifies whether the authentication information is correct based on the information including the first device ID, the first device private key, the second device ID, and the second device public key.
5. The method of claim 3, wherein before the first device obtains authentication information from the second device, the method further comprises:
the first device sends the first device ID to the second device;
the first device obtains the first information, which is obtained by the second device through searching in the block chain based on the first device ID, from the second device, where the first information is the information release content released by the first device.
6. The method according to any of claims 4-5, wherein the first information and the second information are pre-stored in the blockchain and the third information is pre-stored locally to the second device.
7. An information distribution apparatus, characterized in that the apparatus comprises:
the generating module is used for generating an information release request and information release content corresponding to the information release request, and specifically used for performing hash operation on a first device public key and a first device ID which are pre-stored locally to obtain a digest value; performing digital signature operation on the digest value based on a first device private key which is pre-stored locally to obtain a signature result; combining the digest value and the signature result according to a first preset format to generate an information release request; combining the first equipment ID and the first equipment public key according to a second preset format to generate information release content;
the searching module is used for searching a block chain, when a pre-stored information release request which is the same as the information release request does not exist in the block chain, the information release request is released to a block chain network, and the block chain network is waited to write the information release request into the block chain;
a first judging module, configured to search the block chain, and judge whether a pre-stored information distribution content identical to the first device ID or the first device public key included in the information distribution content exists in the pre-stored information distribution content;
the second judgment module is used for performing hash operation based on the information release content to obtain an abstract value of the information release content and judging whether a target information release request with the same abstract value as the information release content exists in prestored information release requests stored in the block chain or not when the first judgment module judges that the information release content does not exist;
and the execution module is configured to, when the second determination module determines that the first device private key included in the signature result of the target information distribution request matches the first device public key included in the information distribution content, distribute the information distribution content to the block chain network, and wait for the block chain network to write the information distribution content into the block chain.
