Abstract
An integrated circuit device comprises a processor and a secure protection zone with security properties that can be verified by a remote device communicating with the integrated circuit device. The secure protection zone includes a persistent storage that is configured for storing cryptographic keys and data. The secure protection zone also includes instructions that are configured for causing the processor to perform cryptographic operations using the cryptographic keys. In addition, the secure protection zone includes an ephemeral memory that is configured for storing information associated with the cryptographic operations. The instructions are configured for causing the processor to perform the cryptographic operations on the data stored in the persistent storage and the information in the ephemeral memory as part of a secure communication exchange with the remote device.
