We are looking a person who can customize and write security dongle (with driverless HID device)
What we need:
1)A simple and a cheap solution with USB interface (with driverless HID device ) and a microprocessor / smart card chip solution(low cost ~ 5$) design.
2) A PCB layout
3) Embedded software with chosen items which includes these scenerio;
Dongle must have a unique ID
When PC software asks this ID, dongle must send this ID
!!PC software will write private key once!!! then for all of the sign operations will use this private key in Dongle.
(This private key should be in safe in all time and conditions with copy-protected)
and scenario is basic: PC software sends a string to dongle, and dongle signs this string and send back signed string to PC Software.
