1 is a diagram illustrating an edge cloud system 100 for log verification between heterogeneous operators according to an embodiment of the present invention.

Referring to FIG. 1 , the edge cloud system 100 includes a Cloud Service Customer (CSC) terminal 110 , an edge node 120 , a broker server 130 , a Cloud Service Provider (CSP) server 140 and It may include a Network Provider (NP) server 150 .

The edge node 120 may provide the service provided by the CSP server 140 to the CSC terminal 110 connected to the edge node 120 . In this way, since the edge node 120 provides a service close to the CSC terminal 110, a service demonstration time may be reduced. Here, the service may mean a cloud server.

In one embodiment, since the edge node 120 provides a service near the CSC terminal 110 based on virtualization technologies such as containers and virtual machines, the edge node 120 generates log data for the edge service. can

The broker server 130 may periodically monitor, ie, monitor, log data generated while providing the edge service to the CSC terminal 110 . In addition, the broker server 130 may deliver a status report on the quality of service (QoS) violation or compliance for the edge service to the CSP server 140 .

In this case, the service provision form in the logging framework may be performed after the service provider that provides the infrastructure, that is, the NP server 150 and the other operator in the corresponding infrastructure, that is, the CSP server 140, deploy the service.

At this time, in the conventional case, it is difficult to access because each operator has a different logging area, and it is also difficult to secure the reliability of whether log data is tampered with when the CSP server 140 requests the NP server 150 for QoS compliance. Therefore, as in the present invention, there is a broker server 130, which is a third party acting as an arbiter between two operators, so that the service QoS can be guaranteed.

The CSP server 140 manages the edge nodes it owns, and provides and manages the service so that the edge node 120 existing near the CSC terminal 110 can provide the service.

In an embodiment, the CSP server 140 and the NP server 150 may enter into a service level agreement (SLA) contract before service distribution.

In the conventional case, in the edge cloud system, the operator providing the service and the operator providing the infrastructure exist at the same time to provide the service to the user. In such a conventional environment, log data is accumulated in different areas and cannot be accessed from each other, so it is impossible to check whether each log data has been tampered with.

Therefore, the present invention is a broker-based logging framework that can verify logs through the broker server 130 that can accumulate all log data for different logging areas of two operators in the edge node 120, and provides complementary reliability. can be improved

In addition, the present invention that can be applied to the edge cloud system 100 is a domestic situation such as the phenomenon of providing a service together between the CSP server 140 and the NP server 150 in addition to the situation in which mobile edge computing (MEC) is being introduced. As services and ecosystems expand, it can be used where integrated management of all logs of both businesses is required.

In an embodiment, the edge cloud system 110 may further include a Distributed-Storage Cluster (DSC) server (not shown).

DSC server can distribute log data. In an embodiment, the DSC server may refer to a storage service group that can be distributed and stored so that the grouped log data cannot be checked externally.

For example, the DSC server may mean a service provider that can receive a storage service through a security API, such as a CSP, a web hard service provider, or a storage service provider.

The DSC server means a storage where the log data generated by each edge node 120 is divided and stored in a distributed manner, the divided log data is stored through the Secure API, and the stored divided log is read-only. ) can be read by anyone.

2 is a diagram illustrating a frame structure for log verification between heterogeneous operators in the edge cloud system 100 according to an embodiment of the present invention.

Referring to FIG. 2 , the CSC terminal 110 may receive a service from the closest edge node 120 . In addition, the CSC terminal 110 may request a complaint from the CSP server 140 when a service error occurs during service use.

When the edge node 120 provides a pre-arranged cloud service to the CSC terminal 110 , log data may be generated in the edge node 120 . The edge node 120 may collect and log log data generated through the blockchain network and transmit it to the broker server 130 at regular intervals.

The CSP server 140 may provide a service to the edge node 120 near the CSC terminal 110 that wants to receive the service through a wide area network (WAN) and manage the edge node 120 connected thereto. . The CSP server 140 may receive a monitoring report from the broker server 130 to check the QoS violation and compliance.

The broker server 130 may collect and integrate logs generated in the edge cloud service. When a security event or service error occurs, the broker server 130 may provide a report for checking whether QoS is complied with to the CSP server 140 .

3 is a diagram illustrating a signal flow for log verification between heterogeneous operators in the edge cloud system 100 according to an embodiment of the present invention.

Referring to FIG. 3 , in step S301 , the edge server 120 may transmit log data for an edge service to the broker server 130 . In one embodiment, log data may be transmitted periodically.

In step S302 , the broker server 130 may transmit the log data storage completion response to the edge server 120 after storing the received log data.

In step S303 , the edge server 120 may detect an abnormal state of the edge service. For example, the edge node 120 may detect that an event in which the service cannot be performed due to hardware failure, server error, etc. occurs during cloud service.

In step S304 , the edge server 120 may receive a service request of the edge service from the CSC terminal 110 .

In step S305 , if the edge server 120 fails to provide the edge service to the CSC terminal 110 due to an abnormal state of the edge service, the CSC terminal 110 informs the CSP server 140 that the edge service is not provided. can be sent.

For example, the CSC terminal 110 may receive only an error message when requesting a service from the adjacent edge node 120 and may not be able to use the service. Accordingly, the CSC terminal 110 may put a complaint about the service availability to the CSP server 140 .

In step S306 , the CSP server 140 may transmit a status report request for the edge servers to the broker server 130 in response to receiving the service non-provision notification.

That is, the CSP server 140 may request a QoS report to check the QoS violation and compliance with the corresponding edge node 120 that cannot provide the service.

In step S307 , in response to receiving the status report request, the broker server 130 may generate a status report for the edge service using log data.

In step S308 , the broker server 130 may transmit a status report for the edge service to the CSP server 140 .

That is, according to the present invention, the CSP server 140 checks the QoS violation and compliance through the broker server 130 as a third party, so that the broker-based logging framework of the present invention is the NP server 150 and the CSP server 140 . ) can improve liver reliability.

Referring to FIG. 4 , log data for an edge service may be received from the edge server 120 . In this case, log data may be partitioned and grouped and then encrypted.

For example, referring to <Equation 1> below, log data is an Internet Protocol address (IP) address of the edge node 120 , an IP address of the CSC terminal 110 , and a Media Access (MAC) of the CSC terminal 110 . Control Address) address, ID (identification) of the CSC terminal 110, ID of the CSP server 140, service time, service URI (Uniform Resource Identifier) may include.

)로 분할할 수 있다. 또한, 그룹핑(partitioning) 단계(420)에서, 엣지 노드(120)는 다수의 로그 세그먼트를 다수의 로그 세그먼트 그룹(

)으로 그룹핑할 수 있다. Referring to FIG. 4 , in a segmentation step 410 , the edge node 120 divides log data into a plurality of log segments (

) can be divided into In addition, in the grouping (partitioning) step 420 , the edge node 120 divides a plurality of log segments into a plurality of log segment groups (

) can be grouped.

In an embodiment, the log data may be divided according to the performance of the edge node 120 and sensitivity information of the log data.

In an embodiment, log data may be grouped according to various methods, such as a round robin method, a range partitioning method, a hashing partitioning method, a list partitioning method, and the like.

For example, log data may be divided and grouped as shown in Equation 2 below.

),

is the mth log segment group (

),

is a function for splitting log data into log segments,

denotes a function for grouping log segments into log segment groups.

That is, existing logging systems protect data confidentiality by encrypting and storing log data in a local storage, but since the edge node 120 has limited computing resources, an overload problem may occur due to log encryption.

Therefore, as in the present invention, in order to protect the confidentiality of log data while preventing the performance degradation of the edge node 120, the edge node 120 may divide the log data into small units in which information recognition is impossible. .

Also, the edge node 120 may transmit and store the grouped log data to DSC servers (not shown) in a distributed manner. That is, each of a plurality of log segment groups can be transmitted and stored in a distributed manner to the corresponding DSC servers.

The edge node 120 may generate a log index for a plurality of log segment groups. For example, the log index may be generated as in Equation 3 below.

는 m번째 로그 엔트리의 다수의 로그 세그먼트 그룹에 대한 로그 인덱스,

is the log index for multiple log segment groups of the mth log entry,

is the mth log segment,

denotes path information for the k-th log segment group.

In addition, since storing log data in the edge node 120 may result in tampering and loss due to an attacker, the edge node 120 stores the divided log data in a distributed manner in the DSC server, and divides and stores the divided log data. One piece of information can be created as an index file.

Also, the edge node 120 may encrypt the log index. For example, the log index may be encrypted as in Equation 4 below.

represents the log index.

In other words, since index data is shared with other users to ensure the integrity of the log index, partitioned data blocks can be recombined through the shared log index. In addition, the log index may be encrypted with the user's public key to protect confidentiality and privacy from malicious investigators and other CSP servers. In addition, the ID of the CSC terminal 110 and the log generation time may be recorded together in the log index for easy search.

Also, the edge node 120 may transmit the encrypted log index to the broker server 130 . In other words, the edge node 120 may transmit the encrypted log index to the broker server 130 capable of preserving data integrity.

In an embodiment, log data for an edge service may be received from the edge server 120 in an unencrypted state without being divided or grouped.
