A system and method for ensuring or verifying the integrity of data transmitted between protection domains. When the data is transmitted, it may be received in a different logical configuration (e.g., as a different number of “chunks”). The receiving domain computes its data integrity metadata (e.g., checksum, CRC, parity) on its form of the data using its protection scheme (e.g., checksum algorithm), and also applies the sending domain's protection scheme to the data as it was received from the sending domain. Similarly, the sending domain applies the receiving domain's protection scheme to compute data integrity metadata on the transmitted data as it appears in the receiving domain. The metadata may be compared to determine whether the data was corrupted during the transfer. Either domain may forward its data integrity metadata to the other, which may store and/or forward it as needed.
