In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, a schematic structural diagram of an implementation environment of the industrial internet according to various embodiments of the present invention is shown. The implementation environment includes: user terminal 120, blockchain network 140, data security gateway 160, and industrial field device 180.
The user terminal 120 may be a mobile phone, a tablet computer, an electronic book reader, a portable computer, a desktop computer, and the like.
The industrial field devices 180 form an industrial control system, the industrial control system can control intelligent devices such as machine tools, robot arms and robots to carry out industrial production, and the control system can ensure the normal and credible operation of the devices safely.
The blockchain network 140 is constructed by adopting a distributed point-to-point technology based on a database technology constructed by a distributed book technology, and the blockchain network 140 has the characteristics of non-falsification, safety and credibility.
The blockchain network 140 performs data interaction with the user terminal 120, displays parameter states of various systems and devices in the industrial field, and controls the intelligent device connected to the industrial field device 180; the block chain network 140 is configured by using a virtualization technology to construct a plurality of distributed block chain nodes, each block chain node is connected with a cloud server database, and the nodes are mutually verified by constructing a small-world network, so that the credibility of each node is ensured. The block chain nodes generate blocks through a consensus mechanism, verify the blocks, encrypt and store verified data packets to the cloud server database in a block chain centerless storage mode, and achieve data sharing in a mode of executing intelligent contracts.
The smart contract is constructed with a control (control) as a basic element, and the control is a basic control unit of the industrial control system network and represents control of the industrial field device 180 by a controller. A control process typically consists of a set of interrelated controls.
Specifically, control is a five-tuple C (p, e, C, r, tc) meaning that the person p (person) issues a command to the industrial field device 180 (command), and if command C (command) is reached, the result r (result) is produced. Where the values of instruction c and result r are boolean values. A value of true indicates that the instruction has been completed (or the result has been completed), a value of false indicates that the instruction has not been completed (or the result has not been completed); and tc (time-constraints) represents the validity period of the control, and tc is true, so that the control is effective.
There may be 5 different states within a control lifecycle.
Activation (activation): both instruction c and result r are false and the time does not exceed the validity period of the control. Indicating that control is active, waiting for the completion of instruction c and the completion of result r;
ready (ready): the instruction c is true, the result r is false, the time does not exceed the validity period of the control, the control is effective, the instruction c is achieved, and the completion of the result r is waited;
(III) satisfies (satisfy): instruction c and result r are both true, indicating that instruction c has been reached, result r has also been completed, and control has been fulfilled;
(IV) expired (expire): both instruction c and result r are false, and the time has exceeded the validity period of the control. Indicating that instruction c failed to complete and result r failed to complete in the event of control failure;
and (V) default that instruction c is true, but result r is false, and the time exceeds the validity period of the control. Indicating that when control fails, its control completion result r has been violated despite the fact that instruction c has been reached.
Wherein, the control validity period is a two-tuple tc: (cact, cbas), wherein, cact represents the completion time limit of the instruction c after the control enters the activation state; cbas represents a completion time limit for result r after control enters the ready (ready) state. If the two limits are met, tc is true; otherwise, tc is false.
Wherein, an action can be expressed as action: (actionname, object, input, output), where: actionname is the name of the action, execute is the executor of the action, object is the action object of the action, input is the input parameter, output is the output parameter (act, execute is required, and object, input and output are all optional). The value of the action is a boolean value, action _ false indicates that the action is not completed, and action _ true indicates that the action is completed. The default value for the action is false.
An industrial internet intelligent contract is a finite automaton SC defined over a set of controls: is (CC, A, S, S)0δ, F), wherein CC ═ C1，C2，...，CnIs a limited control set;
a is the set of actions involved in these controls (including timeout actions, i.e., time out of control's validity period); s ═ S0，s1，s2，...，smIs a finite set of states. The state si is determined by all the controlled states in the CC;
s0 is an initial state, where all controls in the CC are either in an active state (conditional control) or a ready state (unconditional control);
s is the state change function A, the committed state in the CC is prompted to change by the action in the state transition function A, and the state of the intelligent contract is caused to change;
f ∈ S is a limited set of termination states.

Each block link point manages N data security gateways 160, each data security gateway 160 is managed by M block link points, wherein N is more than or equal to 1, and M is more than or equal to 2; when a certain block link point fails due to a fault, the other block link points complete the communication with the user terminal 120 and the data security gateway 160 at the same time; in the M block link points corresponding to one data security gateway 160, the 1 block link point closest to the data security gateway is selected as a target block link node, and is responsible for the communication between the data security gateway 160 and the user terminal 120, so as to improve the communication efficiency.
An asymmetric encryption algorithm is adopted between the block chain link point and the data security gateway 160 to generate a digital signature for data and encrypt the data; the digital signature is used for verifying the authenticity of the data and whether the data is tampered, and the data is encrypted so that the data can only be received by a determined receiver.
The asymmetric encryption algorithm consists of a private key and a public key, and when the public key is used for encryption, the corresponding private key is used for decryption, and when the private key is used for encryption, the corresponding public key is used for decryption;
the data encryption process is as follows: the data is subjected to double SHA256 operation to generate a 32-bit unique hash value, then the hash value is encrypted by using a private key to generate a digital signature, and the digital signature and the data are encrypted by using a public key of a receiver to obtain encrypted data.
The private key production process relies on the chip ID and encryption algorithm of the internal processor of data security gateway 160, among other things, to ensure the uniqueness and non-tamperable nature of the device private key. The private key is stored by the device and is not allowed to leave the storage device, and the public key is used as a block chain to uniquely manage the identifier for the device. The computer program accepts only the confirmed status of the blockchain and controls the industrial field device 180.
The block chain nodes achieve consensus through a workload proving consensus mechanism, the block chain link point which firstly completes workload proving operation obtains the right of generating a new block and becomes a main node of the consensus process, the rest of block chain nodes are block chain slave nodes, the block chain slave nodes verify the block generated by the block chain master node, the data consistency is ensured, and the block chain link point which firstly completes workload proving operation next time becomes the new block chain master node;
the block chain master node broadcasts the generated new block to the block chain slave nodes, the block chain slave nodes verify the new block and reply a verification result and a data signature to the block chain master node, the block chain master node collects the reply result, and according to the principle that minority obeys majority, if the block is approved by the majority of the block chain nodes, the block chain master node rebroadcasts the new block and the verification result, and the block chain slave nodes store the new block.
The intelligent contract is executed by the block chain nodes to realize data sharing among the industrial field devices 180, the intelligent contract specifies the data sharing condition, the condition is formulated by a data provider, the target block chain node executes the intelligent contract, the data is encrypted according to the output result of the constraint condition and then sent to a certain data security gateway 160, and the data security gateway 160 receives and decrypts the data to complete the corresponding task.
The invention realizes the security protection of the industrial internet control system network and the control credible security of the industrial internet control system based on the block chain intelligent contract technology and the data security gateway 160 with the built-in block chain intelligent contract Dapp.
