Abstract
An integrated circuit includes a system memory, a security processor and a non-security processor. An attack against the integrated circuit is made more difficult based on using a key generated by the security processor. The security processor, as an example, reads a program image from the system memory and generates the key based on the program image. In some instances, a dedicated communication channel is provided for communication between the non-security processor and the security processor. The dedicated channel may be used to provide the key to the non-security processor for performance of a security operation.
