DIFTV: Dynamic Information Flow Tracking on RISC-V

By: Kejun Chen, Yier Jin

Stage: RTL

Summary

• A framework to detect the software attacks at run-time.
• Implemented as a coprocessor which attached to the RISC-V processor core Rocket-Chip.
• The committed instructions will be sent to the coprocessor for further analyzing.
• The security check policy is customized based on the custom RISC-V instructions.
• The related information flow will be check according to the customized security policy.
