System, device and method for secure provision of key credential information

Abstract

A system for secure provision of key credential information is provided. The system comprises secure logic circuitry for being disposed in a host computer. The secure logic circuitry detects a message received from a remote computer connected to the host computer and indicative of a request for provision of the key credential information; generates a message for prompting a user for provision of the key credential information; receives the key credential information; and provides the key credential information to the remote computer absent processing using circuitry of the host computer. The system further comprises a secure user interface cormected to the secure logic circuitry for receiving the key credential information from the user and providing the same to the secure logic circuitry.

1 . A system for secure provision of key credential information comprising:
 secure logic circuitry for being disposed in a host computer, the secure logic circuitry for:   detecting a message received from a remote computer connected to the host computer and indicative of a request for provision of the key credential information;   generating a message for prompting a user for provision of the key credential information receiving the key credential information; and,   providing the key credential information to the remote computer absent processing using circuitry of the host computer; and,   a secure user interface connected to the secure logic circuitry for receiving the key credential information from the user and providing the same to the secure logic circuitry.   
     
     
         2 . A system for secure provision of key credential information as defined in  claim 1  wherein the secure user interface comprises:
 a secure display for displaying the message for prompting the user for provision of the key credential information; and,   a secure keyboard for providing the key credential information.   
     
     
         3 . A system for secure provision of key credential information as defined in  claim 1  wherein the secure logic circuitry is placed on a network interface card. 
     
     
         4 . A system for secure provision of key credential information as defined in  claim 3  wherein the secure user interface is provided as a peripheral device connected to the network interface card. 
     
     
         5 . A system for secure provision of key credential information as defined in  claim 1  wherein the secure logic circuitry comprises a processor and memory, the memory having executable commands stored therein for execution on the processor. 
     
     
         6 . A method for secure provision of key credential information comprising:
 using a secure logic circuitry disposed in a host computer, detecting a message received from a remote computer connected to the host computer and indicative of a request for provision of the key credential information;   using the secure logic circuitry, generating a message prompting a user for providing the key credential information;   using a secure user interface connected to the secure logic circuitry, receiving the key credential information from the user and providing the same to the secure logic circuitry;   using the secure logic circuitry, providing the key credential information to the remote computer absent processing using circuitry of the host computer.   
     
     
         7 . A method for secure provision of key credential information as defined in  claim 6  comprising:
 using the secure logic circuitry, generating display data for displaying the message prompting the user; and,   using a display of the secure user interface displaying the message prompting the user.   
     
     
         8 . A method for secure provision of key credential information as defined in  claim 6  comprising scanning messages received from the remote computer for detecting the message indicative of a request for provision of the key credential information. 
     
     
         9 . A method for secure provision of key credential information as defined in  claim 7  comprising interrupting transmission of keystroke signals from a keyboard connected to the host computer to the circuitry of the host computer. 
     
     
         10 . A method for secure provision of key credential information as defined in  claim 6  comprising:
 interrupting communication between the circuitry of the host computer and the remote computer after detection of the message indicative of a request for provision of the key credential information; and,   enabling the communication between the circuitry of the host computer and the remote computer after provision of the key credential information to the remote computer.   
     
     
         11 . A method for secure provision of key credential information as defined in  claim 6  comprising using the secure logic circuitry, encoding the key credential information for provision of the same in an obfuscated fashion. 
     
     
         12 . A device for providing secure key credential information comprising:
 key credential information request detection means connected to a host computer adapted for detecting a message received from a remote computer connected to the host computer and indicative of a request for provision of the key credential information;   secure logic circuitry for being disposed within the host computer and adapted for receiving key credential information from a user and providing same to the remote computer while not providing key credential information to any other processor of the host computer; and   keyboard means adapted for receiving the key credential information from the user and providing the same to the secure logic circuitry.   
     
     
         13 . The device according to  claim 12  having display means connected to the key credential information request detection means and adapted for generating a message for prompting the user for provision of the key credential information in response to the detection of a message received from the remote computer connected to the host computer and indicative of a request for provision of the key credential information.
