Abstract: An example system includes a secure processing engine. The secure processing engine is to store a host key. The system also includes an integrated circuit in a single package. The integrated circuit includes a firmware engine to execute firmware instructions. The integrated circuit also includes a one-time-programmable (OTP) memory unreadable by the firmware engine. The OTP memory is to store the host key. The integrated circuit also includes a security engine. The security engine is to encrypt and decrypt communications between the firmware engine and the secure processing engine based on the host key.
