Abstract
A compact hardware key for protecting software executing on a computer is disclosed. The hardware key uses a two piece insulator design in which each insulator piece provides a double layer insulator body for protection from tampering, insulator areas for electrically isolating I/O connector pins, and an integral circuit board support portion for securely mounting the circuit board assembly. The compact hardware key also comprises a unique coaxially displaced interrupt pin structure.
