Patent ID: 8001591

Claim:
A method comprising: determining, at a first requesting component of an integrated circuit device, a first key value based on a first set of one or more bits of a first address associated with a first access request of the first requesting component, wherein determining the first key value comprises accessing a first key table associated with the first requesting component, the first key table comprising a plurality of key value entries indexed based on the first set of one or more bits; transmitting the first key value from the first requesting component to a resource component of the integrated circuit device; determining, at the resource component, an authorization of the first access request based on the first key value and a second set of one or more bits of the first address; determining, at a second requesting component of the integrated circuit device, a second key value based on a third set of one or more bits of a second address associated with a second access request of the second requesting component; transmitting the second key value from the second requesting component to the resource component of the integrated circuit device; and determining, at the resource component, an authorization of the second access request based on the second key value and a fourth set of one or more bits of the second address.
