Abstract: An integrated circuit chip is provided which contains one or more processors and one or more cryptographic engines. A flow control circuit having a command processor accepts requests and data via a secure external interface through which only encrypted information is passed. The flow control circuit mediates decryption of this information using cryptographic keys that are present in hard coded form on the chip. In particular the flow control circuit includes a programmable hardware portion which is configurable in a secure manner to create a flexible internal chip architecture. The chip also includes a volatile memory disposed on a voltage island on which is maintained either through a battery backup or from a fixed power source (mains). The chip is thus enabled to securely perform cryptographic operations with the processors controlling the cryptographic engines through the flow control circuit.
