Secure Communication Port Redirector

摘要

A method and system that allows a host system application to securely communicate with a legacy device is provided. A redirector software module receives data that is destined for a host system serial COM port. Data is secured and re-directed to a legacy device via a network port instead of the serial COM port. Conversely, data destined for the host system is provided to a device server via a server COM port by the legacy serial device. The data can be encrypted and sent to the host system via the network. The redirector software module decrypts the encrypted data and presents it to the consumer application as if the data had arrived via the local COM port.

1. A method for moving data from a host computer system across a network to a remote device, comprising:
waiting for a send event corresponding to application data stored on a non-transitory computer readable storage medium of the host computer system being transmitted to a serial communications port on the host computer system; intercepting the application data from an application stored on the host computer system before transmission of the application data over the serial communications port; encrypting the application data; signaling the send event, which indicates that the encrypted application data is available for transmission to the remote device; transmitting, upon detection of the send event, the encrypted application data over a network interface to the remote device via a communication stack interface; receiving device data originating from the remote device via the communication stack interface; decrypting the device data, if necessary, upon determining that the device data needs to be decrypted; and providing the device data to the application on the host computer system.
