Problems solved by technology

Taking card readers as an example, common card readers usually only contain functional modules, without considering the issue of security management
When the card reader is installed on the terminal of the application device, on the one hand, the device can be opened to various business uses, and at the same time, it may also be used by various malicious software or Trojan horse programs, which brings great security risks to the use of sensors.

Abstract

The embodiment of the invention discloses a safety access method for a sensor. The method comprises the following steps: when monitoring that service software calls service of the sensor, intercepting the service calling of the service software; acquiring a signature configuration file of the service software, wherein the signature configuration file comprises a program file and a signature ciphertext; calling a code signing certificate in the sensor to authenticate and sign the signature configuration file; and when the signature configuration file is authenticated and signed successfully, calling the service of the sensor through the service software. Correspondingly, the embodiment of the invention also provides a sensor, an application equipment terminal of the sensor and a safety access system. The implementation of the safety access method can realize the safety access management of sensor equipment, and avoids potential safety hazard caused by calling the sensor by various malicious software or a Trojan program.

Description

technical field [0001] The invention relates to the technical field of applied electronics, in particular to a method for securely accessing a sensor, a sensor and a system for securely accessing. Background technique [0002] With the development of radio frequency technology and sensor technology and the promotion of products, more and more sensors have entered various industries, including card readers, USB_Key, etc. At the same time, the security management of sensor devices is facing more and more challenges. Taking card readers as an example, common card readers usually only contain functional modules, without considering the issue of security management. When the card reader is installed on the terminal of the application device, on the one hand, the device can be opened to various business uses, and at the same time, it may be used by various malicious software or Trojan horse programs, so it brings great security risks to the use of sensors. .
