Abstract
Approaches for bridging communication between first and second buses are disclosed. Address translation information and associated security indicators are stored in a memory. Each access request from the first bus includes a first requester security indicator and a requested address. Each access request from the first bus and directed to the second bus is either rejected, or translated and communicated to the second bus, based on the requester security indicator and the security indicator associated with the address translation information for the requested address. Each access request from the second bus to the first bus includes the requested address, and the access request is translated and communicated to the first bus along with the security indicator that is associated with the address translation information for the requested address.
