Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide an IP soft core authorization method based on a block chain, so as to ensure the security of the IP soft core authorization and further relatively reduce the occurrence of IP soft core piracy. The other core of the invention is to provide an IP soft core authorization device and medium based on the block chain.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
Fig. 1 is a flowchart of an IP soft core authorization method based on a block chain according to an embodiment of the present invention. Referring to fig. 1, the specific steps of the block chain-based IP soft core authorization method include:
step S10: and responding an authorization application of the application end to the target IP soft core through the authorization end, and performing Hash operation on a source code of the target IP soft core to generate a first Hash value.
It should be noted that, since the authorization of the target IP soft core is applied, and the entity form of the target IP soft core is a code, after the authorization application of the application end to the target IP soft core is responded, the Hash operation is performed according to the source code of the target IP soft core to generate the first Hash value. In addition, the execution subject of the present invention may be a specific authorization end, that is, a device node having an authorization qualification of an IP soft core, and may also be regarded as a control system for regulating and controlling authorization steps between the authorization end and the application end at present, but the final purpose is to authorize the application end IP soft core, and therefore the execution subject is not particularly limited.
Step S11: and generating a digital signature according to the first Hash value, and transmitting the digital signature and a preset authorization condition to the application end.
The digital signature is one-side data that can be generated only by the sender and cannot be forged by others, and is also a valid proof of authenticity of information transmitted by the sender. In the step, the digital signature is obtained by encrypting the first Hash value by using a private key of an authorization end, and the characteristic is that the authorization end is an authorized party of the target IP soft core. In addition, the authorization condition in this step should be predefined by the authorization end, and the authorization condition may specifically be a condition on the identity or a condition on the performance of the application end.
In addition, in the invention, the source code of the target IP soft core can be transmitted to the application end together with the digital signature and the authorization condition, or the source code can be defaulted to be already existed in the application end. In addition, the transmission referred to in the present application should be asymmetric transmission, that is, the sending end encrypts the original data through the public key of the receiving end, and then after transmitting the encrypted data to the receiving end, the receiving end decrypts the encrypted data according to its own private key to obtain the original data, so as to ensure the security of data transmission.
Step S12: and when the application end meets the authorization condition and the digital signature is verified to be legal according to the source code, broadcasting the authorization record to the nodes in the block chain network so as to add the nodes into the block chain, and completing the authorization of the target IP soft core.
It should be noted that the purpose of verifying the validity of the digital signature according to the source code is to verify whether the IP soft core in the application end is the same as the IP soft core to be authorized by the authorization end, so as to ensure that the content of the IP soft core is not changed. Only when the digital signature is verified to be legal and the application end meets the authorization condition, the accuracy and the reliability of authorization can be ensured. When the application end meets the authorization condition and the digital signature is verified to be legal according to the source code, the authorization record is broadcasted to the nodes in the block chain and added into the block chain of each node, the purpose is to perform distributed storage on the authorization record representing authorized through a block chain mechanism, and then each node in the block chain network, which stores the authorization record, is an authenticator for authorizing the target IP core.
Step S13: and when the application terminal uses the target IP soft core, performing authorization check on the application terminal according to the authorization record in the block chain.
It can be understood that, because the blockchain mechanism has strict consensus among nodes, the same authorization record can be recorded and acknowledged by a plurality of nodes together, and is difficult to modify, when the application end uses the target IP soft core, the authorization check is performed on the application end through the authorization record in the blockchain, so that it can be ensured that the authorization record is prevented from being forged or copied, and the authorization reliability is improved.
The IP soft core authorization method based on the block chain provided by the invention generates a digital signature according to a source code of the target IP soft core after responding an authorization application of an application end to the target IP soft core, and transmits a preset authorization condition and the digital signature to the application end, and then broadcasts an authorization record to a node in the block chain network to add into a block chain of the node when the application end verifies that the digital signature is legal and meets the authorization condition, thereby completing the authorization of the target IP soft core. And after the authorization is finished, when the application end uses the target IP soft core, performing authorization check on the application end according to the authorization record in the block chain. It can be seen that, when the method authorizes the IP soft core, the authorization record is broadcasted to the nodes of the block chain network and added to the block chain of each node, because the block chain mechanism has strict data consensus, the authorization record is added to each node of the block chain network, which is equivalent to that each node commonly sees the authorization state of the IP soft core, and when the application end uses the IP soft core, the application end is authorized and checked through the authorization record in each node block chain, so that the possibility of forging and copying the authorization file is reduced, the security of the authorization of the IP soft core is ensured, and further the occurrence of the piracy of the IP soft core is relatively reduced.
Example two
On the basis of the above examples, the present invention also provides a series of preferred embodiments as follows.
As a preferred embodiment, before generating the digital signature from the first Hash value, the method further comprises:
and performing digital summarization on the first Hash value.
It should be noted that the purpose of the digital abstract is to convert data of an arbitrary length into short data of a fixed length. Considering that the data length of the first Hash value generated by the source code of the target IP soft core is often high, and the processing pressure for generating the digital signature according to the Hash value is high subsequently, the digital digest can be performed on the first Hash value before the digital signature is generated according to the first Hash value, so that the data length of the first Hash value can be further shortened, the calculation pressure for generating the digital signature is reduced, and the overall efficiency is improved.
As a preferred embodiment, the specific steps of the application end verifying the digital signature according to the source code include:
the application end carries out Hash operation on the source code to generate a second Hash value, and analyzes the digital signature to obtain a first Hash value;
judging whether the first Hash value is the same as the second Hash value;
if so, the digital signature is legitimate.
It can be understood that, since the application end has the source code of the target IP soft core, and the purpose of performing data signature verification is to verify the accuracy of the authorized target IP soft core, so as to prevent the IP soft core to be authorized by the application end from being different from the IP soft core to be authorized by the authorization end, and the Hash value can reflect the difference between the data to the greatest extent, the application end verifies the digital signature according to the source code, and needs to perform Hash operation on the source code to generate a second Hash value, and then compares the second Hash value with the first Hash value analyzed by the received digital signature, if the first Hash value is completely consistent with the second Hash value, the digital signature is legal, that is, it is stated that the IP soft core to be authorized by the application end is the same as the IP soft core to be authorized by the authorization end.
As a preferred implementation, both the application end and the authorization end are in the blockchain network.
It should be noted that, in view of the fact that the method is mainly based on a block chain mechanism, authorization records are stored in nodes of a block chain network in a distributed manner to achieve authorization of the IP soft core, and communication between an application end, an authorization end, and nodes in the block chain network is involved, when the application end and the authorization end are also in the block chain network, overall efficiency of data transmission between the application end and the authorization end and other nodes in the block chain network can be relatively improved, and on this basis, overall efficiency of the IP soft core authorization can also be improved.
On the basis of the above embodiment, as a preferred embodiment, the authorization condition is specifically that the number of tokens at the application end is greater than or equal to a preset value;
accordingly, before broadcasting the authorization record to a node in the blockchain network, the method further comprises:
and correspondingly modifying the UTXO of the application terminal and the authorization terminal according to the preset value, and writing the UTXO of the application terminal and the authorization terminal into an authorization record.
It should be noted that the token is an important component of the blockchain mechanism, and is a reward for stimulating the operation of each node in the blockchain operation, and each value token is produced and distributed differently, so that the token has a corresponding value in the blockchain. The token quantity is used as an authorization condition to be more matched with the general working purpose of each node in the blockchain network, so that more nodes can be promoted to be added into the blockchain network for working. In addition, it should be noted that the UTXO is an abbreviation of an un-consumed Transaction Output, and the UTXO can be used to record token transfer in a block chain, and has an advantage of small size, thereby ensuring the overall operation efficiency of the block chain mechanism. The specific working process of the application end and the authorization end is that the application end locks the UTXO of the application end and modifies a preset value through a locking script, and signs through a private key of the application end, so that the UTXO of the application end is broadcasted in a block chain network; after receiving the UTXO of the application terminal, the authorization terminal analyzes the UTXO through a private key thereof and verifies the signature, and correspondingly modifies the UTXO after the verification is passed so as to finally complete the modification of the UTXO of the application terminal and the authorization terminal.
As a preferred embodiment, after broadcasting the authorization record to nodes in the blockchain network, the method further comprises:
and after the broadcast confirmation messages of the 6 nodes are acquired, writing the authorization record into a database.
It should be noted that, because the number of nodes in the blockchain network is generally large, when data broadcasting is performed in the blockchain network, the broadcasting initiating node transmits data to other nodes in direct communication with itself, and then the other nodes continue to transmit data to nodes in direct communication with other nodes, and after the other nodes in the blockchain network receive the data of the initiating node, a broadcast confirmation message is sent to the initiating node to indicate that the data is received. Since writing the authorization record into the block chain of each node is the essence of the method for authorizing the IP soft core, the authorization record can be determined to be successfully recorded in the block chain network through a certain number of broadcast confirmation messages. In this embodiment, the number of times of the broadcast acknowledgement message defining that the authorization record is successfully recorded by the blockchain is set to 6, and after the broadcast acknowledgement messages of 6 nodes are acquired, the authorization record is written into the database. It should be noted that the database herein specifically refers to a database outside the blockchain mechanism of the authorization end or the overall control system, and is used for performing independent statistics of authorization records locally, so as to facilitate viewing or use.
EXAMPLE III
In the above, the embodiment of the IP soft core authorization method based on the block chain is described in detail, and the present invention further provides an IP soft core authorization apparatus based on the block chain corresponding to the method.

And the authorization checking module 13 is configured to perform authorization checking on the application end according to the authorization record in the block chain when the application end uses the target IP soft core.

And after the authorization is finished, when the application end uses the target IP soft core, performing authorization check on the application end according to the authorization record in the block chain. It can be seen that when the device authorizes the IP soft core, the authorization record is broadcasted to the nodes of the block chain network and added to the block chain of each node, because the block chain mechanism has strict data consensus, the authorization record is added to each node of the block chain network, which is equivalent to that each node commonly sees the authorization state of the IP soft core, and when the application end uses the IP soft core, the application end is authorized and checked through the authorization record in each node block chain, so that the possibility of forging and copying the authorization file is reduced, the security of the authorization of the IP soft core is ensured, and the occurrence of the piracy of the IP soft core is relatively reduced.

And after the authorization is finished, when the application end uses the target IP soft core, performing authorization check on the application end according to the authorization record in the block chain. It can be seen that when the device authorizes the IP soft core, the authorization record is broadcasted to the nodes of the block chain network and added to the block chain of each node, because the block chain mechanism has strict data consensus, the authorization record is added to each node of the block chain network, which is equivalent to that each node commonly sees the authorization state of the IP soft core, and when the application end uses the IP soft core, the application end is authorized and checked through the authorization record in each node block chain, so that the possibility of forging and copying the authorization file is reduced, the security of the authorization of the IP soft core is ensured, and the occurrence of the piracy of the IP soft core is relatively reduced.
