Referring to FIG. 1 , the common door management system apparatus 110 according to the present invention includes a housing database 111 , a location information request unit 112 , a apartment house confirmation unit 113 , and a transmission unit 114 .

In the housing database 111, location information on each of a plurality of pre-designated apartment houses and an access key value corresponding to each of the plurality of apartment houses are stored in correspondence with each other.

Here, the key value for access means a preset key value used to open a common door existing in each of the plurality of apartment houses. In relation to such an access key value, a user who intends to open a common door may open the common door by directly entering the access key value as a password into the door opening/closing control device mounted on the common door, and may open the common door. is stored in a terminal capable of short-distance communication, and then the terminal is brought close to the door opening/closing control device so that the access key value is transmitted to the access opening/closing control device, thereby opening the common door.

For example, information may be stored in the housing database 111 as shown in Table 1 below.

multiple condominiums location information key value for access Apartment 1 location information 1 Access key value 1 apartment house 2 geolocation 2 Access key value 2 apartment house 3 geolocation 3 Access key value 3 ... ... ...

In this situation, the first delivery source 30, which is one of a plurality of delivery sources pre-designated to use the common door management service according to the present invention, is any one of the plurality of apartment houses, the first apartment house 10 ), when a situation arises in which the first common door 20 installed in the first apartment house 10 needs to be opened, the first delivery person 30 has An open request command for the common door may be transmitted to the common door management system device 110 using the first delivery person terminal 100 .

In this way, when a command to open a common door is received from the first delivery source terminal 100 possessed by the first delivery person 30 among a plurality of pre-specified delivery sources to the common door management system device 110, the location The information requesting unit 112 requests to transmit the current location information of the first delivery agent terminal 100 to the first delivery agent terminal 100 .

Then, the first delivery agent terminal 100 collects location information on the current location of the first delivery agent terminal 100 by utilizing a location information collection module such as GPS mounted on the first delivery agent terminal 100 . After doing this, it may be transmitted to the common door management system device 110 .

The apartment house confirmation unit 113 is the current location information collected by the first delivery source terminal 100 from the first delivery source terminal 100, and when the first location information is received, it is stored in the housing database 111. A first apartment having location information according to the shortest separation distance from the location according to the first location information among the plurality of apartment houses by comparing the location information for each of the plurality of apartment houses with the first location information Check the house (10).

That is, the apartment house confirmation unit 113 is the first apartment house 10 that the first delivery agent 30 is currently trying to deliver the apartment house located closest to the current location of the first delivery source terminal 100 . can be checked with

In this way, when the first MDU 10 is confirmed, the transmitter 114 transmits the first MDU among the key values for access corresponding to each of the plurality of MDUs stored in the housing database 111 . 10) extracts the first entry/exit key value and transmits the first entry/exit key value to the first delivery person terminal 100 .

In this way, when the first delivery key value corresponding to the first apartment house 10 is received in the first delivery agent terminal 100 , the first delivery agent 30 sends the first delivery agent terminal 100 to the first delivery agent terminal 100 . The first common access door 20 may be opened using the first access key value received through the .

Specifically, the first delivery person 30 may open the first common door 20 by directly inputting the first access key value as a password to the door opening/closing control device mounted on the first common door 20 . can In addition, if it is said that the first delivery source terminal 100 is a terminal equipped with a module capable of short-distance communication, and that the door opening/closing control device is also equipped with a short-range communication module, the first delivery source 30 ) is when the first delivery source terminal 100 receives the first access key value, the first delivery agent terminal 100 is brought close to the door opening/closing control device mounted on the first common door 20, By allowing the first access key value received by the first delivery person terminal 100 to be transmitted to the door opening/closing control device, the first common door 20 may be opened.

According to an embodiment of the present invention, the joint door management system device 110 exposes the first access key value to the outside in the process of transmitting the first access key value to the first delivery person terminal 100 . In order to prevent this from happening, the method may further include a configuration for encrypting the first access key value and transmitting it to the first delivery person terminal 100 .

In this regard, the transmission unit 114 is a configuration for encrypting the first access key value and transmitting it to the first delivery person terminal 100, the delivery agent database 115, the extraction unit 116, and the encryption unit 117 and a transmission processing unit 118 .

In the delivery source database 115 , pre-issued delivery source identification values for each of the plurality of delivery sources are stored.

In this case, a delivery source identification value for each delivery source may be pre-issued and stored in a delivery source terminal owned by each of the plurality of delivery sources.

For example, information may be stored in the delivery source database 115 as shown in Table 2 below.

multiple couriers Shipper Identification Value Shipper 1 Shipper Identification Value 1 shipper 2 Shipper Identification Value 2 shipper 3 Shipper Identification Value 3 ... ...

When the first apartment house is confirmed by the apartment house confirmation unit 113 , the extraction unit 116 is configured to select the first one among the key values for access corresponding to each of the plurality of apartment houses stored in the housing database 111 . The first access key value corresponding to the apartment house is extracted.

When the first access key value is extracted, the encryption unit 117 extracts the first delivery source identification value for the first delivery source 30 from the delivery source database 115 and then converts the first delivery source identification value to the first delivery source identification value. Based on the encryption of the first access key value, an encryption value for the first access key value is generated.

At this time, according to an embodiment of the present invention, the encryption unit 117 uses a preset encryption key for homomorphic encryption for each of the first delivery source identification value and the first access key value. By performing homomorphic encryption, a first isomorphic ciphertext for the first delivery source identification value and a second isomorphic ciphertext for the first access key value are generated, and then the first By performing an isomorphic operation between the homomorphic ciphertext and the second homomorphic ciphertext, an encryption value for the first access key value may be generated.

Homomorphic encryption refers to an encryption technology that supports operations between data in an encrypted state without decrypting the encrypted data. In other words, homomorphic encryption refers to an encryption technology that allows obtaining the same value as the result of calculating data in the plaintext state when the result value calculated in the encrypted state is decrypted.

For example, suppose that plaintext data of A and B exist, that E(A) is encrypted data generated by isomorphic encryption of A, and E(B) is encrypted data generated by isomorphic encryption of B. At this time, if it is assumed that a predetermined operation is performed on E(A) and E(B) and an operation value called E(S) is calculated, when E(S) is decoded, the decoded value is the sum of A and B The basic concept of isomorphic encryption is to make it equal to the value multiplied by That is, when a value calculated by performing a predetermined operation on two encrypted data in the encryption domain is decrypted, encryption such that the decrypted value matches the value calculated by calculating the two plaintext data in the plaintext domain is called homomorphic encryption.

In this regard, in order to generate an encryption value for the first access key value, the encryption unit 117 first performs homomorphic encryption for each of the first delivery source identification value and the first access key value. By performing homomorphic encryption using a preset encryption key, it is possible to generate a first isomorphic ciphertext for the first delivery source identification value and a second isomorphic ciphertext for the first access key value.

Then, the encryption unit 117 performs an isomorphic operation between the first isomorphic ciphertext and the second isomorphic ciphertext according to a preset first homomorphic ciphertext, thereby generating an encryption value for the first access key value. can

'를 복호화한 결과는 '

'와 같아지게 된다. 이러한 관계가 성립할 때, 상기 제1 동형 연산식인 동형 곱셈은 평문 도메인에서의 곱셈에 대응되는 관계가 있다고 말할 수 있다. 여기서, 동형 곱셈은 평문 도메인에서의 곱셈과 같이, 단순히 암호화된 두 데이터를 곱하는 형태의 연산이 수행되는 것은 아니다. 동형 곱셈은 평문 도메인에서의 곱셈과 대응되는 결과를 만들기 위한 동형 연산식이기 때문에, 단순히 암호화된 두 데이터를 곱하는 형태의 연산 과정이 이루어지는 것이 아니라, 동형 암호화의 특성에 따라 곱하기, 더하기, 모듈로 연산 등이 복합적으로 수행되는 소정의 연산 알고리즘으로 정의될 수 있다.Here, the first isomorphic expression is an expression for performing an operation between two data on which homomorphic encryption has been performed, and may be preset by a developer. The first isomorphic operation expression refers to an operation expression designated to generate a result corresponding to a predetermined operation expression performed between two plaintext data in the plaintext domain in the encryption domain. For example, when there is an arithmetic expression called multiplication that multiplies plaintext data with each other, there may be an isomorphic multiplication corresponding to the multiplication. In this regard, it is said that plaintext data A and B exist, A and B are homomorphically encrypted, respectively, and encrypted data E(A) and E(B) are generated, and the first isomorphic operation expression is in the plaintext domain. In the case of isomorphic multiplication corresponding to multiplication, if E(A) and E(B) are homogeneously multiplied in the cryptographic domain, '

' can be generated, and when A and B are multiplied in the plaintext domain, '

' may be generated. At this time, '

The result of decoding ' is '

' will be the same as When such a relationship is established, it can be said that the isomorphic multiplication as the first isomorphic expression has a relationship corresponding to the multiplication in the plaintext domain. Here, homomorphic multiplication is not performed in the form of simply multiplying two pieces of encrypted data, like multiplication in a plaintext domain. Since homomorphic multiplication is an isomorphic arithmetic expression for creating a result corresponding to multiplication in the plaintext domain, the operation process of multiplying two encrypted data is not performed, but multiplication, addition, and modulo operations are performed according to the characteristics of homomorphic encryption. and the like may be defined as a predetermined arithmetic algorithm that is complexly performed.

In this way, when the encryption unit 117 generates an encryption value for the first entry/exit key value, the transmission processing unit 118 transmits the encryption value for the first entry/exit key value to the first delivery service terminal 100 . By transmitting, the transmission of the first access key value to the first delivery source terminal 100 is completed.

In this case, the first delivery agent terminal 100 may pre-store the first delivery agent identification value in the memory of the first delivery agent terminal 100 , and the first delivery agent terminal 100 from the joint door management system device 110 . When the encryption value for the entry/exit key value is received, based on the first delivery person identification value stored in the memory of the first delivery agent terminal 100, the encryption value for the first entry/exit key value is obtained from the encryption value. The first access key value may be restored.

At this time, according to an embodiment of the present invention, the first delivery source terminal 100 pre-stores the first delivery source identification value in the memory of the first delivery source terminal 100, and at the same time, the encryption key may be additionally stored in advance of a decryption key corresponding to , and when an encryption value for the first access key value is received from the common access door management system device 110 , it is stored in the memory of the first delivery person terminal 100 . After generating a decrypted value by decrypting the encryption value for the first access key value using the decryption key stored in Accordingly, a solution such that an operation result calculated when calculation is performed with the first delivery source identification value stored in the memory of the first delivery agent terminal 100 becomes the same as the decryption value By calculating the result of the restoration of the first entry/exit key value, the first entry/exit key value may be restored.

By calculating a solution to be equal to ', 'B', which is the first entry/exit key value, may be restored. That is, in the first delivery agent terminal 100, since the first arithmetic expression is multiplication, the result calculated when 'A', which is the first delivery agent identification value, is multiplied by a certain value is '

By calculating a solution to become ', 'B', which is the first entry/exit key value, may be restored.

According to an embodiment of the present invention, the joint door management system device 110 may further include a location information receiving unit 119 , a deletion command transmitting unit 120 , an updating unit 121 , and an update command transmitting unit 122 . can

When the transmission of the encryption value for the first access key value to the first delivery agent terminal 100 is completed, the location information receiving unit 119 receives the first delivery agent terminal 100 from the first delivery agent terminal 100 at a preset first cycle interval. 1 Receives location information of the delivery person terminal 100 .

The deletion command transmission unit 120 receives the encryption value for the first access key value at the first interval or when a preset first elapsed time has elapsed from the time when the encryption value is transmitted to the first delivery service terminal 100 . When it is confirmed that the location according to the location information of the first delivery person terminal 100 is out of a preset radius from the location according to the location information for the first apartment house 10 stored in the housing database 111 , transmits, to the first delivery person terminal 100 , a deletion command instructing to delete the encryption value for the first access key value transmitted to the first delivery agent terminal 100 .

For example, when the first elapsed time is '30 minutes' and the preset radius is '2 km', the deletion command transmission unit 120 transmits the encryption value for the first access key value to the first delivery When it is confirmed that '30 minutes' has elapsed from the time of transmission to the original terminal 100, or the location of the first delivery person terminal 100 is out of a radius of '2 km' from the location of the first apartment house 10 , by transmitting a deletion command instructing to delete the encryption value for the first access key value to the first delivery person terminal 100 , the first access key value for the first apartment house 10 . It can be prevented in advance from being used at a point unrelated to delivery.

When the deletion command is transmitted to the first delivery agent terminal 100, the update unit 121 generates a random identification value for updating the first delivery agent identification value as a new delivery agent identification value, and then the delivery agent database The first delivery source identification value stored in 115 is replaced with the new delivery source identification value.

Thereafter, the update command transmission unit 122 transmits the new delivery source identification value to the first delivery source terminal 100 , and the first delivery source stored in the memory of the first delivery source terminal 100 . Send an update command instructing to replace the identification value with the new shipper identification value.

At this time, when the first delivery source terminal 100 receives the new delivery source identification value and the update command from the joint door management system device 110 , the first delivery source identification value stored in the memory is converted into the new It can be replaced with the shipping source identification value.

In this way, after the first delivery source identification value is replaced with the new delivery source identification value in the delivery agent database 115 and the first delivery agent terminal 100 , the first delivery agent 30 is given another joint When the process of providing an access key value for opening a common door existing in a house is in progress, the common door management system device 110 encrypts the access key value based on the new delivery source identification value to first It may be provided to the delivery person terminal 100 .

In this way, the joint door management system device 110 according to the present invention may update the delivery source identification value for the delivery person to a new identification value whenever the key value for access is provided to the delivery person, and through this, By enabling the access key value to be encrypted with a different type of encryption value each time, security can be enhanced in the process of providing the access key value.

2 is a flowchart illustrating a method of operating a common door management system device according to an embodiment of the present invention.

In step S210, location information on each of a plurality of pre-designated apartment houses and an access key value corresponding to each of the plurality of apartment houses (the key value for access is a joint existing in each of the plurality of apartment houses) It maintains a housing database in which the preset key values used to open the door are stored in correspondence with each other.

In step S220, when a command to open a common door is received from a first delivery agent terminal possessed by a first delivery person among a plurality of pre-specified delivery sources, the first delivery agent terminal is sent to the first delivery agent. Requests to transmit the current location information of the terminal.

In step (S230), when the first location information is received as the current location information collected by the first delivery source terminal from the first delivery source terminal, for each of the plurality of apartment houses stored in the housing database By comparing the location information and the first location information with each other, the first MDU having location information according to the shortest separation distance from the location according to the first location information among the plurality of MDUs is identified.

In step S240, if the first apartment house is identified, a first access key value corresponding to the first apartment house among the access key values corresponding to each of the plurality of apartment houses stored in the housing database and transmits the first access key value to the first delivery person terminal.

At this time, according to an embodiment of the present invention, in step S240, the step of maintaining a delivery source database in which pre-issued delivery source identification values for each of the plurality of delivery sources are stored, the first apartment house is If it is confirmed, extracting the first access key value corresponding to the first apartment house from among the access key values corresponding to each of the plurality of apartment houses stored in the housing database; When the key value is extracted, the first delivery source identification value for the first delivery source is extracted from the delivery source database, and then encryption is performed on the first access key value based on the first delivery source identification value. generating an encryption value for the first access key value, and when the encryption value for the first access key value is generated, the encryption value for the first access key value is transmitted to the first delivery person terminal By transmitting, it may include the step of completing the transmission of the first access key value to the first delivery person terminal.

In this case, the first delivery source terminal pre-stores the first delivery source identification value in the memory of the first delivery source terminal, and an encryption value for the first access key value from the common door management system device When this is received, the first access key value can be restored from the encryption value for the first access key value based on the first delivery source identification value stored in the memory of the first delivery source terminal have.

At this time, according to an embodiment of the present invention, the generating of the encryption value is homogeneous encryption using a preset encryption key for homogeneous encryption for each of the first delivery source identification value and the first access key value. By performing, after generating a first homomorphic ciphertext for the first delivery source identification value and a second homomorphic ciphertext for the first access key value, the first isomorphic ciphertext according to a preset first homomorphic ciphertext An encryption value for the first access key value may be generated by performing isomorphic operation between the second homomorphic ciphertext and the second homomorphic ciphertext.
