Abstract
In an embodiment, a system is provided in which the private key is managed in hardware and is not visible to software. The system may provide hardware support for public key generation, digital signature generation, encryption/decryption, and large random prime number generation without revealing the private key to software. The private key may thus be more secure than software-based versions. In an embodiment, the private key and the hardware that has access to the private key may be integrated onto the same semiconductor substrate as an integrated circuit (e.g. a system on a chip (SOC)). The private key may not be available outside of the integrated circuit, and thus a nefarious third party faces high hurdles in attempting to obtain the private key.
