Hardware Security Locking ID Device (TAPA)

     TAPA is a system (connecting to the parallel printer port) that limits the use of software applications to those who purchase them legally. It is also used by Internet based solutions (E-commerce, ID-Password based sites, etc.) for users to identify themselves by a 100% secure way. It offers ease-of-use, transparency and security. TAPA was developed for the printer interface of the PC. In its development, special attention was paid to transparent behaviour.

Components

    

5 MIPS 8bit RISK CPU!!!! (MIPS = Million Instructions Per Second!)

48 bit real time clock (1 tick = 1/3 580 000 sec. = precision!)

Real RANDOM Generator!

IDEA32 Crypt engine.

2 * 128 bit - user defined passwords (for IDEA32 stream)

64 bit user defined ID code.

48 bytes EEPROM (100000 erase/write cycles)!

HOW TAPA WORKS

     1) Default Mode of TAPA is "Passive" The TAPA is transparent for the printer and other devices which may come after it (other security devices for example).
2) Commands to the TAPA:
The TAPA has its own CPU with 2 own registries:

REG_Command (BYTE)

REG_Operand (BYTE)

The user communicates with the TAPA via C++ subroutines provided in a DLL file (for experts) or via easy to use maintanence software for the non programmers.
3) Activating the TAPA (switch to "Active" mode) is done with the help of the maintenance easy to use software.
NOTE: When the TAPA is activated it checks the state of the lines from the printer to the computer (if there is printer installed) and it remains transparent for the printer, i.e. the printer can be used without any problems while the TAPA is active.

APPLICATION OF TAPA

     TAPA has 2 main applications:

To lock software by a 100% sure way, and make it usable by users who have legally purchased it.

Be used to encrypt information, store passwords, private keys and electronic certificates for use in authentication solutions for LANs, VPNs, eCommerce and mobile computing. Its functionality enables companies to eliminate costly deployment issues, and maximize user-friendliness without compromising security.
