Problems solved by technology

This function specifically points out that: the caller must have administrator privileges; therefore, under Windows system, administrator privileges are required when accessing the peripheral smart password device, while Windows limited users do not have administrator privileges. In this way, the smart password device cannot be accessed without UAC

Embodiment 1

[0023] The method of accessing the smart password device under the limited user of the WINDOWS system: establish a memory channel in the system through the Windows pipeline technology, which can be accessed by different processes; in the Dll dynamic link library, create a named pipe for use with the Service The service program does inter-process communication; the pipe is opened in the Dll dynamic link library, the command data for manipulating the smart cryptographic device is sent to the pipe and the data returned by the smart cryptographic device is received from the pipe; the named pipe is opened in the Service service program, and the data in the pipe is received. Command data, access and interact with the smart cryptographic device on the server side, and then send the data returned by the smart cryptographic device to the pipeline.

[0024] The pipeline created in the Dll dynamic link library, after use, closes the pipeline in time and releases related resources; the pip...

Abstract

The invention discloses a method for accessing an intelligent password device under a WINDOWS system limited user. The method comprises the steps of: in a dynamic link library (Dll), establishing a named pipe for performing interprocess communication on the named pipe and a Service program; opening the pipe in the Dll, transmitting the command data for controlling the intelligent password device to the pipe and receiving data returned by the intelligent password device from the pipe; and opening the named pipe in the Service program, receiving the command data in the pipe, accessing and interacting the intelligent password device in the service program end, and transmitting the data returned by the intelligent password device to the pipe. The method provided by the invention is implemented by related technologies such as combining system service, pipe communication Dll and system resource object permission setting. The method can be implemented only by invoking the Dll interface and is simple and convenient in operation. The method is applicable to access of different upper application on the device.

Description

technical field [0001] The invention relates to the technical field of access rights to system resource objects, in particular to a method for accessing intelligent cryptographic devices for limited users of the WINDOWS system. Background technique [0002] A dynamic link library (Dll) is a way to realize a shared function library in the Windows operating system and is the basis of the Windows operating system. In actual programming, we can put the function that completes a certain function in a dynamic link library, and then provide it for other programs to call, and it can be called by different programming languages. [0003] A Windows service (Service) is a computer program that runs in the background. Created to follow specific rules and protocols, and can be assigned administrator privileges. It can be configured to run automatically when the operating system starts up. While the operating system is running, the service program will always run in the background. ...
