Problems solved by technology

[0003] It is usually very difficult for users to distinguish whether the application program held by the user is an application program provided by a legitimate application provider or a tampered application program
It is believed that when the tampered application is executed, serious damage such as data destruction or leakage of on-site confidential data to a malicious third party occurs

Embodiment approach

[0023] The data processing system according to the present embodiment is a system for processing data transmitted from a device. The data processing system is installed in a factory as a product production system. Data processing by the data processing system is performed, for example, to detect and reject defective products from the manufacturing process, to classify materials, or to monitor abnormalities. In the data processing system, the user sets the contents of the processing performed on the data. figure 1 Shows the hardware structure of the data processing system. The data processing system includes devices 201 and 202 that operate in a product manufacturing process, and a data processing device 100 that processes data sent from the devices 201 and 202 .

[0024] The data processing apparatus 100 is connected to the devices 201 and 202 via the network 210 , and communicates with the devices 201 and 202 by sending and receiving signals. Both the data processing appar...

Abstract

A data processing system characterized by comprising a verification means 521 which verifies an application program 310 including authentication data 303 that has been encrypted in advance using a first private key 301 retained by an authentication organization, wherein the verification means 521: acquires dynamic information 402, which is information loaded into a memory 403 when a verification function 122 included in the application program 310 is executed; and verifies the application program 310 by comparing the dynamic information 402 with verification dynamic information 302, which is obtained by decrypting the authentication data 303 using a first public key 401 associated with the first private key 301 retained in advance.

Description

technical field [0001] The present invention relates to a data processing system, a data processing device and a verification method of an application program having a verification function of an application program. Background technique [0002] In recent years, in facilities represented by factories, the management and improvement of production processes, inspection processes, and other processes have been realized by collecting and processing data from within the facilities. In the industrial world, there is an increasing tendency to analyze the data collected in the field and apply it to the field for improvement. Along with this, a platform serving as the basis of a system for analyzing data to implement improvement activities, or an application program that operates in cooperation with the platform to collect and analyze data are provided to users. [0003] It is generally very difficult for the user to distinguish whether the application program held by the user is a...
