In a first aspect, as shown in fig. 1, the present disclosure provides a shared battery, which mainly includes an electric energy storage module, a processor module, and a network communication module;
the electric energy storage module is mainly used for storing electric energy and recording battery information; the processor module is mainly used for acquiring the battery information of the shared battery, generating authentication information according to the battery information and adding the authentication information into the block chain according to an authentication result; or, the battery safety state is verified according to the identity verification information, and the battery information is added according to the verification result of the battery safety state; the network communication module in the battery is mainly used for transmitting and receiving data, for example, broadcasting the authentication information of the shared battery in the block chain.
In a second aspect, as shown in fig. 2, based on the shared battery in the first aspect, the present application provides a method for sharing a battery, which includes steps S100-S400:
s100, acquiring battery information of a shared battery, and generating identity verification information according to the battery information;
specifically, in the embodiment system, the battery information of the shared battery includes, but is not limited to, a factory date of the battery, a factory number of the battery, an ID of the shared battery, and the like, which can form an identity uniquely identifying the battery; the number of times of charging and discharging the battery, usage records, battery life, and other state information used to characterize the state of health or life of the battery. The identity authentication information is authentication information obtained by integrating battery information of the shared battery and through an encryption algorithm.
S200, broadcasting the identity authentication information to a block chain, and verifying the safety state of the battery by a first node of the block chain according to the identity authentication information;
the first node is a shared battery equipment node which already exists in the block chain; before adding a shared battery into a blockchain network, firstly, according to a preset cycle time, regularly confirming whether a new node (namely a new shared battery) in a blockchain is ready to be added into the blockchain or not, under the condition that the new node or the shared battery is determined to be added, broadcasting the authentication information of the shared battery in the blockchain nodes so that all the nodes in the blockchain can obtain the authentication information of the shared battery, decrypting and carrying out security verification on the authentication information according to a decryption algorithm corresponding to the encryption algorithm, verifying whether the battery information of the shared battery is tampered or not or whether a digital signature is correct or not so as to determine whether the shared battery is safe and credible or not, and if the verification is passed, allowing the shared battery to be added into the blockchain as the new node of the blockchain. It should be noted that some possible embodiments may also perform verification on information broadcast in the block chain during the verification process, determine whether the broadcast information is authentic, and add the shared battery to the block chain after determining that the broadcast information is authentic and the authentication information is verified.
S300, adding the battery information to the first node according to the verification result of the battery safety state;
specifically, after the security status verification is performed in step S200, it is determined that the information of the shared battery to be newly added to the blockchain is safe and reliable, and the node information of the shared battery to be newly added to the blockchain is recorded in the already existing nodes in the blockchain, where the node information includes, but is not limited to, the battery information of the shared battery and/or broadcast information in the blockchain.
S400, generating a second node to be added into the block chain, wherein the second node is used for representing the shared battery;
in one embodiment, the second node is a block or node that is to be added to the blockchain to characterize the shared battery. Specifically, in the embodiment, a new node or a new block of the shared battery is generated according to the corresponding workload certification algorithm and added to the block chain, so that corresponding node/block information is acquired in a subsequent process of using the shared battery.
In some optional embodiments, the authentication information generated in step S100 may not include, but is not limited to: battery state information, battery identification information, communication information and a digital signature;
the battery state information may include, but is not limited to, data such as the number of charge and discharge times, the remaining capacity, and the usage time of the battery of the current shared battery cached in the processor module of the shared battery. The battery identification information may include identification information such as a battery ID, a communication module ID of the shared battery, and an ID of the electric energy storage module, where the aforementioned identification information is identification information determined by a manufacturer when the battery leaves a factory. The communication information may include communication information such as an IP address, a gateway, and a device number of the network communication module sharing the battery. In the embodiment, the processor module encrypts the battery information to be broadcasted (Encryption) with a private key obtained by an Encryption algorithm, and a receiver, namely other nodes or blocks in the block chain, decrypts the battery information to be broadcasted (Decryption) by using a public key broadcasted by the shared battery, so that the authenticity, integrity and non-repudiation of the information can be ensured.
In an embodiment, the specific digital signature calculation process is as follows: a signature (hash (number of charge and discharge times | remaining amount of electricity | used time | communication module ID | battery ID)) -a sign (hash (number of charge and discharge times | used time | communication module ID | battery ID)). The Hash algorithm compresses input data of any length through the algorithm, and outputs fixed-length data with a much smaller size, namely a Hash value. The hash value is also called a Digital Fingerprint (Digital Fingerprint) or a Message Digest (Message Digest) of the input data, and the obtained Message Digest is used as a Digital signature in the authentication information.
In some possible embodiments, the process of verifying the safety state of the battery according to the authentication information in step S200 may include at least one of the following two steps:
step S210, the battery identification information and the communication information are verified according to historical data, and a first mapping relation between the battery identification information and the communication information is determined to be the same as a second mapping relation in the historical data;
specifically, in the embodiment, before a new shared battery is added to the block chain as a new block, the history data stored in the existing node in the block chain includes a correspondence relationship between the battery ID of each shared battery and the communication module ID inside the shared battery, that is, a second mapping relationship; when the safety state of the newly added shared battery is verified, each block compares the second mapping relation which is locally stored with the corresponding relation between the battery ID carried in the battery identification information broadcasted in the block chain and the communication module ID, namely the first mapping relation, determines that the first mapping relation and the second mapping relation are communicated, and passes the primary verification.
Step S220, verifying the digital signature according to a public key;
specifically, in the embodiment, after the newly added shared battery passes the primary verification, the digital signature in the authentication information of the newly added shared battery needs to be verified for the second time; in some possible embodiments, step S220 may then include steps S221-S223:
s221, decrypting the digital signature through the public key to obtain a second message digest;
s222, acquiring broadcast information in the block chain, and determining a third message digest of the broadcast information through the hash function;
s223, determining that the second message digest is the same as the third message digest;
specifically, the digital signature obtained by encrypting in step S100 is acquired, and this digital signature information is attached to the information of the to-be-transmitted broadcast when broadcasting is performed in the block chain, and is broadcast together. After the receiver, namely a node in the block chain, receives the broadcast information, on one hand, the public key is adopted to decrypt the digital signature to obtain a summary H; on the other hand, the received broadcast information itself is hashed to obtain another digest H ', and then H and H' are compared to see if they are the same. According to the characteristics of the hash function, a short abstract can be used for representing the information, and if the two abstracts H and H' completely conform to each other, the information is proved to be complete; if the information is not in accordance with the information, the information is indicated to be maliciously tampered by others.
In some possible embodiments, the shared battery adding method may further include steps S500-S600:
s500, acquiring the shared battery use record and transaction information;
s600, broadcasting the use record and the transaction information to a block chain, and storing the use record and the transaction information to the first node and the second node;
specifically, the usage record of the battery and the transaction record may be stored in the processor module in the shared battery, where the generation process of the transaction record specifically is: the user selects the shared battery ID required to be replaced according to the returned information, then the battery is replaced, the user verifies the battery ID before the replacement is completed, after the user verifies the battery ID successfully, the credit mortgage transaction is executed, the transaction starting time is recorded, and the transaction starting time is recorded in each block node of the block chain; after the user replaces and uses the shared battery, the shared battery needs to be returned, the steps S100-S400 are carried out in the returning process, the returned shared battery is subjected to security verification, the transaction ending time is determined after the verification is passed, then the complete transaction information record is obtained, the user mortgage is returned, and the transaction information is completely recorded in each block node of the block chain.
In a third aspect, as shown in fig. 3, the present application further provides a method for using a shared battery, which includes steps T100-T200:
t100, acquiring a battery replacing request;
t200, obtaining a second node in the block chain according to the battery reloading request, and determining a shared battery according to battery information in the second node;
the generation process of the second node is as follows:
acquiring battery information of a shared battery, and generating identity verification information according to the battery information;
broadcasting the identity authentication information to a block chain, and verifying the safety state of the battery by a first node of the block chain according to the identity authentication information;
and according to the verification result of the battery safety state, adding the battery information at the first node, generating a second node and adding the second node to the block chain.
