Abstract
A key block can be generated from a session key used by a computer-based design tool for a circuit design by encrypting the session key using computer hardware. The key block can be divided, by the computer hardware, into a plurality of sub-blocks. A plurality of enhanced sub-blocks can be generated by the computer hardware by encrypting each sub-block of the plurality of sub-blocks with a different key of a plurality of keys corresponding to a plurality of Intellectual Property (IP) cores of the circuit design. The plurality of enhanced sub-blocks can be stored in a memory.
