Description
Technical Field
The invention relates to the field of intelligent locks, in particular to an enterprise-level intelligent lock system based on electronic key issuing.
Background
The unlocking process of the intelligent lock can be divided into three steps. And the first step of unlocking constraint downloading, namely, issuing control information of who unlocks when to unlock the lock or the key, and checking when to unlock the lock. And the second step of verification of unlocking constraint, namely verifying whether the biological characteristic information of an unlocking person is matched or whether the corresponding verification codes are consistent or not, verifying whether the unlocking person is unlocked within a specified time or not and the like when the unlocking is performed. And thirdly, performing unlocking mechanical operation, rotating a gear inside the lock cylinder, and releasing the lock beam by the lock tongue.
The common intelligent electronic lock is generally completed by only one lock body, and the downloading, verification and unlocking of unlocking constraint are completed in one lock. However, such electronic locks often have multiple motherboard modules, are bulky, and are self-contained or connected to a power source. Therefore, the mechanical lock core is far from the mechanical lock core, and cannot cover most of the application range of the mechanical lock, for example, a drawer for storing files, and therefore, the mechanical lock cannot consume extra manpower to charge regularly, and cannot be provided with a socket capable of providing power. Moreover, the lock has large volume, and the space condition required by additionally installing the lock is more harsh, thereby affecting the beauty. The electronic lock covers a larger range, and some entrance guard locks and the like can be directly plugged in or can intuitively observe the power supply condition and do not consider the situation of the limit of the installation space of the lock.
For this purpose, a passive lock scheme with an electronic key is more commonly used for the enterprise-level lock. The passive lock is a lockset without a power supply, and all operations of the lock cylinder are to provide power by conducting the current of the electronic key through the physical contact between the bolt of the electronic key and the lockset after the electronic key is inserted into the lockset. In addition, because the lockset has no power supply and cannot actively communicate with a background system to download unlocking constraint information, the lockset can further remove the communication module, become lighter, and further add the communication module onto the electronic key to replace the communication by the electronic key. Likewise, modules for unlocking constraint verification, such as fingerprint verification, password entry, etc., can also be migrated from the lock to the key. The size of the lock cylinder of the passive lock which is contacted at present is almost the same as that of a lock cylinder of a mechanical lock, and most of the scenes can be replaced.
However, the above technical scheme of matching the electronic key with the passive lock has a defect that the verification process of unlocking constraint is loosely coupled with the unlocking process in the actual lock core. In short, the verification of unlocking people and unlocking time is carried out in the electronic key, after the electronic key verifies unlocking constraint, an unlocking instruction is simply sent to the lockset, and the lockset drives the lock cylinder to unlock according to the unlocking instruction without any characteristic information serving as a security credential, so that the lockset is unsafe. The unlocking command is replayed or counterfeited, and even if the electric signal of the unlocking command is mastered, a key which can bypass unlocking verification can be manufactured completely to unlock. This is security breached.
The existing intelligent lock system is single in protection type, poor in protection effect and capable of bringing a certain influence to the use of the intelligent lock system, and therefore, the enterprise-level intelligent lock system based on electronic key issuing is provided.

The verification and acquisition of the key and the generation process of the key are as follows:
Electronic key issuing by background system
The background system issues the electronic key, which is equivalent to the process of endorsing the electronic key by a background system, in other words, if the electronic key issued by the background system is the electronic key, the electronic key can be considered as a trusted electronic key at the lockset, and the lockset can safely receive the instruction sent by the electronic key. To implement this procedure we need to use an asymmetric key algorithm whose essence is that there is a pair of public and Private keys Pub and Private, public key Pub being publicly available to the owner, and Private key Private being known only to the owner himself. The things encrypted by the public key Pub can only be decrypted by the Private key Private, and the things encrypted by the Private key Private can also be decrypted and restored by the public key Pub (this can be used to verify whether the other party has the correct Private key, which can be called cryptographically verification).
The background system needs to have a pair of public and private keys server.pub and server.private for issuing keys, and the electronic key also needs to have a pair of public and private keys for marking the identities Key.pub and Key.private. A plurality of electronic keys have a plurality of different public and private keys （Key.pub1、Key.private1）、（Key.pub2、Key.private2）（Key.pub3、Key.private3）..............（Key.pub999、Key.private999）（Key.pubn、Key.privaten）.
The so-called issuing process is that when the background system verifies that an electronic key is a trusted key (possibly by checking the serial code of the device in advance or by preparing the public key of the trusted device in advance), the background system encrypts the public key of the electronic key with its own private key server.
EncryptServer.private(Key.pubn)
The encrypted piece of things can be called a security certificate issued to the electronic key by a background system. The electronic key downloads and saves the certificate.
Because the public key can be distributed to anyone, the public key server. Pub of the background system can also be poured into the lock in advance. When the lockset checks the authenticity of the electronic key every time, a security certificate encryptor. The lockset decrypts the security certificate by using the public key of the background system to obtain the public key of the original electronic key, which is summarized as the following formula
Key.pubn =DecryptServer.pub(EncryptServer.private(Key.pubn))
The lockset only needs to compare whether the public key decrypted by the security certificate is consistent with the public key of the electronic key, so as to judge whether the electronic key is feasible or not and whether the electronic key is issued by a background system or not.
Interaction between electronic key and lockset
We have confirmed that the electronic key is issued by the security system, which is the public key. The interaction between the electronic key and the lock can be performed on the basis of the pair of public and private keys. The interaction needs to use a Symmetric encryption algorithm, and the encryption and decryption of the Symmetric encrypted ciphertext can be completed by using a Symmetric key symmetry, so that the security and the safety of the Symmetric encryption depend on the Symmetric key symmetry to achieve confidentiality and no leakage.
Each time the electronic key is to send an instruction to the lock, a randomly generated symmetric key lock is firstly queried to the lock. The lockset encrypts a private key. Pub of the electronic key and then transmits the electronic key, and the formula is summarized as follows:
EncryptKey.pub(Lock.symmetric)
This symmetric key can then only be obtained by decrypting the electronic key with its own private key, summarized as the following formula
Lock.symmetric = DecryptKey.private(EncryptKey.pub(Lock.symmetric))
After the electronic key obtains the symmetric key, lock. Symmetry, all instructions of the electronic key to the lockset are encrypted by the symmetric key and then transmitted to the lockset, and the following formula is summarized:
EncryptLock.symmetic(instruction)
The lockset can decrypt and obtain the corresponding instruction by using the symmetric key agreed in advance and execute the instruction, and the instruction is summarized as the following formula:
DecryptLock.symmetic(EncryptLock.symmetic(instruction))
Therefore, the interaction between the electronic key and the lockset can be ensured to prevent replay, falsification and interception.
