Abstract

A security device for operating protected programs or data, or other functions performed by or within computers, the security device having both hardware and software keys and a reader for accepting smart cards. The smart card reader communicates with a control module having segmented non-volatile memory. Data from plural smart cards is entered into segmented NVM through the smart card reader. Each segment of segmented NVM creates a virtual token essentially duplicating enabling ability of the corresponding smart card or token. The control module has processing and memory means for encrypting and decrypting commands and recognizing encrypted passwords. The control module also has a plurality of interface apparatuses for enabling communicable connection to computers. When one or more virtual tokens is created by transfer of data from a smart card or cards, the smart card may be safely stored or discarded. A computer connected to the security device may be operated to execute functions which are protected in the sense of access being denied in the absence of keys stored in one or more virtual tokens.

Claims

1. A security device for enabling selected functions to be performed to protected programs or data contained in memory in computers, or other functions performed by or within a computer connected to said security device, said security device comprising:

a smart card reader having means for communicating with a smart card having memory;

a control module having a segmented non-volatile memory, said segmented non-volatile memory including a plurality of segments of non-volatile memory, means for selectively entering enabling data into said plurality of segments of non-volatile memory from a plurality of smart cards, through said smart card reader, recognition means for detecting enabling data entered into each segment of said plurality of segments of non-volatile memory, processing means for enabling execution commands to be operably communicated to selected protected programs or data contained in the memory of a computer connected to said security device responsive to detection of enabling data by said recognition means, processing means for enabling execution commands to allow operation of a computer or specific functions of the computer connected to said security device, and disabling means for preventing execution commands originating at the connected computer to be recognized by said processing means absent detection of enabling data by said recognition means; and

interface means for enabling communication between said control module, said interface means, and a computer connected to said interface means, said interface means including at least one type of interface apparatuses connectable to computers;

whereby a computer user having multiple protected application programs that will not run, unless a physical smart card carrying unlocking means is physically inserted into a smart card reader, may successively physically insert a plurality of physical smart cards into said smart card reader a single time because said unlocking means of each physical smart card is copied and stored in a segment of non-volatile memory in said control module as a virtual smart card and is activated when needed in the absence of a need to reinsert its associated physical smart card.

2. The security device according to claim 1, said recognition means further comprising encryption and decryption means for encrypting enabling data prior to storage of said enabling data in said plurality of segments of non-volatile memory and for recognizing encrypted enabling data entered in said plurality of segments of non-volatile memory, and for enabling execution commands originating at a connected computer to access protected programs or data responsive to recognition of encrypted enabling data entered in said plurality of segments of non-volatile memory.

3. The security device according to claim 1, further comprising means for preventing communication between any two segments of non-volatile memory responsive to commands originating at a connected computer, said means for preventing communication being a separation of each segment of non-volatile memory from all other segments of non-volatile memory.

4. The security device according to claim 1, said control module further comprising automatic recording means for entering enabling data into said plurality of segments of non-volatile memory from said plurality of physical smart cards through said smart card reader.

5. The security device of claim 1, said interface means further comprising a control means for scanning said at least one type of interface apparatuses to determine which interface is in communication with said computer and for translating from one interface protocol to another.

6. The security device of claim 1, said at least one type of interface means further comprising a PCMCIA card socket interface.

7. The security device of claim 1, said at least one type of interface means further comprising a parallel port interface.

8. The security device of claim 1, said at least one type of interface means further comprising a serial port interface.

9. The security device of claim 1, said at least one type of interface means further comprising a universal serial bus interface.
