Description

A five-protection lock management system and method

Technical Field

The present invention relates to the field of five-defense lock management, and in particular to a five-defense lock management system and method.

Background technique

The five protections of electrical equipment mainly refer to: 1. Preventing the accidental closing of switches, 2. Preventing the closing of isolating switches with load, 3. Preventing the accidental entry into live compartments, 4. Preventing the hanging of ground wires with power on, and 5. Preventing the closing of switches with ground wires (grounding switches). For this reason, five protection locks are added to electrical equipment to prevent the occurrence of five protection accidents.

In the prior art, the digital key of the five-defense lock is often stored on the server. When the staff uses it, they log in to the account through the mobile terminal, directly pull the digital key on the server, and then remotely open the five-defense lock. However, because the key is not dynamic and the digital key on the server can be directly obtained in the prior art, the digital key may be leaked by the staff and stolen by attacks, which may cause illegal personnel to open the five-defense lock and steal equipment. At the same time, because the digital key is known to the staff, the staff may not need to go through the server, but directly request the five-defense host to open the five-defense lock, resulting in the inability to form a time record, which may cause accidents (for example, forgetting to close the cabinet door) that cannot be traced.

In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary implementation modes of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

Example 1

As shown in FIG1 , an embodiment of the present invention provides a five-protection lock management system, including a key server, multiple key mobile terminals, a tester, a five-protection host, a five-protection lock, and a device to be operated.

Each key mobile terminal corresponds to a staff member one by one, the key server is communicated with the five-protection host and multiple key mobile terminals respectively, the key terminal is also communicated with the tester, the tester is electrically connected to the device to be operated, the five-protection host is electrically connected to the five-protection lock, the five-protection lock is set on the device to be operated, and the key mobile terminal is equipped with a camera.

The key mobile terminal can be a mobile device such as a mobile phone, a tablet or a notebook, which can realize face recognition while having data processing and data communication power supply. The five-defense lock in this embodiment mainly refers to a five-defense lock that can be opened by remote commands.

In this embodiment, by setting up an electric tester, the staff can obtain the voltage of the device to be operated before the operation. The electric tester can be set to be handheld or fixed. When set to be fixed, it should be fixed on the device to be operated, and its execution end is set on the voltage board of the device to be operated to realize the voltage test of the device to be operated. It is worth noting that the electric tester should have a communication function to transmit the collected voltage generated by the voltage test to the key mobile terminal.

This embodiment sets up a separate key server to generate keys and encrypt based on the device, which ensures the security of the five-defense lock keys and can authenticate the key mobile terminal, ensuring that the staff is related to the task to be operated, and preventing other staff from illegally obtaining the five-defense lock keys. The key mobile terminal is also equipped with a camera that can capture images in real time to achieve face recognition, thereby ensuring that the key mobile terminal is used by the staff himself, further strengthening the relevance of the staff to the task to be operated.

Example 2

As shown in FIG2 , an embodiment of the present invention provides a five-defense lock management method based on a five-defense lock management system, including:

The five-defense host generates pending tasks and transmits the pending tasks to the key server and the corresponding key mobile terminal respectively.

The voltage of the device to be operated is collected by an electric tester to obtain the collected voltage of the device to be operated, and the key mobile terminal is waited to obtain the collected voltage.

The task to be operated is received through the key server, and a first dynamic five-defense key based on the attributes of the five-defense host and a second dynamic five-defense key based on the attributes of the key mobile terminal are generated according to the task to be operated, and the first dynamic five-defense key is transmitted to the five-defense host, and the second dynamic five-defense key is transmitted to the key mobile terminal. The task to be operated includes the attributes of the five-defense host and the attributes of the key mobile terminal corresponding to the task to be operated.

The key mobile terminal obtains the task to be operated, the collected voltage on the electroscope and the real-time portrait, and verifies the staff based on the collected voltage and the real-time portrait. If the verification is successful, the second dynamic five-defense key is received, and the second dynamic five-defense key is decrypted to obtain the first decryption key, which is then transmitted to the five-defense host.

The first dynamic five-protection key and the first decryption key are also received through the five-protection host, the first dynamic five-protection key is decrypted to obtain the second decryption key, and the first decryption key is verified to be the same as the second decryption key. If so, the five-protection lock corresponding to the device to be operated is opened, and the record of the staff opening the five-protection lock is stored. Otherwise, the five-protection lock corresponding to the device to be operated is refused to be opened.

In this embodiment, the next step can only be performed after the power test to ensure the personal safety of the staff. Then, face recognition is performed through the key mobile terminal to ensure that the task to be operated is performed by the staff himself, and the task is associated with the staff. Then, the second dynamic five-defense key based on the key mobile terminal attribute is used to realize device authentication. The key mobile terminal corresponds to the staff one by one. Even if face recognition is not performed, the task can be associated with the staff, and the loss of the digital key on the key server is avoided.

It is worth noting that the five-defense host can also receive a request for reporting the loss of a key mobile terminal generated by human-computer interaction. After the report is lost, the five-defense host sends a message to the key server that the key mobile terminal has been lost, and the five-defense host no longer accepts unlocking requests from the key mobile terminal. The key mobile terminal no longer generates dynamic five-defense keys based on the attributes of the key mobile terminal, and eliminates existing dynamic five-defense keys to prevent the five-defense lock from being opened by illegal personnel.

In a possible implementation, the task to be operated includes a unique task code, staff information, key mobile terminal attributes corresponding to the staff, five-defense host attributes, and a five-defense lock corresponding to the device to be operated.

Optionally, the unique task code may be generated according to a pre-set rule or in response to human-computer interaction.

According to the unique task code in the task to be operated, a first dynamic five-protection key and a second dynamic five-protection key are generated, and the first dynamic five-protection key is the same as the second dynamic five-protection key.

According to the attributes of the five-defense host in the task to be operated, a first dynamic five-defense key based on the attributes of the five-defense host is generated.

According to the key mobile terminal attributes in the task to be operated, a second dynamic five-defense key based on the key mobile terminal attributes is generated.

In a possible implementation, generating a first dynamic five-protection key and a second dynamic five-protection key according to a unique task code in a task to be operated includes:

Randomly extract two digits q and p from the unique task code in the task to be operated. The number of digits in the unique task code is greater than or equal to K. K can be 2, 3, 4, 5, 6, 7 or other larger numbers. There are at least two different digits in the unique task code. The extracted numbers q and p can be different (for example, q and p are mutually prime).

Multiply the number q by the number p to get the number N.

Obtain the least common multiple of the number q-1 and the number p-1 to obtain the number L, L=lcm(p-1,q-1), where lcm represents the least common multiple.

According to the number L, the number E is obtained as:

1<E<L

gcd(E,L)＝1

Among them, gcd means finding the greatest common divisor.

According to the number E and the number L, the number D is obtained as:

1<D<L

E*D mod L＝1

Among them, mod represents the remainder symbol.

The first dynamic five-defense key and the second dynamic five-defense key are randomly composed of the number q, the number p, the number N, the number E and the number D.

Through the above steps, a random first dynamic five-protection key and a second dynamic five-protection key are generated, and the lengths of the first dynamic five-protection key and the second dynamic five-protection key generated each time may be different, thereby increasing randomness.

In a possible implementation, according to the five-defense host attributes in the task to be operated, generating a first dynamic five-defense key based on the five-defense host attributes includes:

According to the attributes of the five-defense host in the task to be operated, an attribute-based encryption algorithm is used to generate a first dynamic five-defense key based on the attributes of the five-defense host.

Randomly select parameter values σ and δ, the elements in the cyclic group G ₁ are γ ₁ ,γ ₂ ,...,γ _u , then the public key PK = {g,g ^σ ,e(g,g) ^δ ,γ ₁ ,γ ₂ ,...,γ _u }, and the private key MSK = g ^δ .

Encryption (PK, m, Γ): Γ is (M, ρ), Γ is associated by the key mobile terminal attributes (or five-defense host attributes) through logical relationship symbols, M represents a l×n matrix, any row in the matrix M is _Mi , i represents the row index of the matrix M, ρ represents an injective function, ρ: {1,...,l}->{1,...,u}. Select a random vector v＝(s,t ₂ ,t ₃ ,...,t _n ), s represents the secret sharing key, t ₂ ,t ₃ ,...,t _n are all random values, λ _i ＝V(M _i ), λ _i represents the secret sharing key share, add information Di _,h to the ciphertext to provide function conditions for the decryption process. The ciphertext is obtained as:

Among them, h∈Γ/ρ(i) means removing the ρ(i) attribute from the associated attributes of the access structure Γ.

Get the user attribute private key (MSK, B): Enter the private key MSK and the key mobile terminal attribute set B, select the random parameter t, and get the attribute private key as:

SK＝{k＝g ^δ g ^-σt ,L＝g ^t }

Among them, any attribute of the key mobile terminal attribute set B is x, and the intermediate parameter

It is worth noting that the attributes in the access structure Γ are the attributes in the task to be operated (that is, the standard attributes of the key mobile terminal stored in the five-defense host), and the key mobile terminal attribute set B is the attributes sent by the key mobile terminal when requesting encryption.

When the key mobile terminal receives the ciphertext CT, the private key SK and the access structure Γ, if the key mobile terminal attribute set B of the key mobile terminal does not satisfy the access structure Γ, decryption cannot be performed, otherwise decryption is performed.

The decryption process can be:

Define the set P = {i:ρ(i)∈B and 1≤i≤l}, and P∈{1,2,...,l}.

Set the target vector to V = (1, 0, ..., 0). According to the linear secret sharing scheme, if the key mobile terminal attribute set B satisfies the access structure Γ, and a set of vectors W = (w ₁ ,w ₂ , ...,w _n ) can be found such that If established, n represents the number of user attributes.

Define the intersection set o = {x: there exists i∈P, x = ρ(i), and x∈B∩Γ}.

Custom functions: Among them, γ(x) represents the attribute value γ _x corresponding to the element in G ₁ , and β(o) represents the multiplication of elements in the attribute set.

Where C _i ′ represents the distribution of the shared key share λ _i on the attribute set o, and the i value of the shared key share λ _i in the ciphertext is distributed through ρ(i) in x∈o/ρ(i).

Wherein, K _o ' represents a continuous product, which is used to continuously multiply the decrypted user private key share K _x , and the β(o) function is substituted into it for derivation.
