Security Gasket to hide transaction to range of addresses for SPA and DPA and secure Data using End-to-End ECC.

Overview

This is a Security and Safety compliance block.

SOC designers/ SW Architects can distinguish memory ranges which may carry sensitive information, which can be leaked out by SPA/DPA.

This block will hide the communication on range of programmed addresses.

Also, it has ECC which is SEC-DED, which will ensure that the transaction is secure while travelling on the backbone system.

One cannot manipulate the secured range of addresses and cannot change data on those addresses.

Key Features

1. AMBA-AXI-4.0 Master and Slave
2. Blocks user to snoop the meaningful data.
3. Block User from SPA/ DPA Gassing the secure data.
4. End to End ECC Secured transactions.
5. ECC is SEC-DED.

Benefits

1. Specified Memory content is protected and secured.
2. Blocks DPA and SPA of Data.
3. Debug ports can snoop Bus Data but cannot make any meaning out.
4. Both Master and Slave components are available.
5. Full Support of standard AMBA-AXI-4.0.
6. Throughput and Performance is 100%.
